feat: global activity feed + session digest

Ops "Executions" tab showed raw target UUIDs, alphabetical (not
recency) order, and a stale status vocabulary from an earlier schema
iteration — never actually usable as a live "what's happening" view.
Replaced with a new recency-ordered /api/v1/activity/recent endpoint
and matching table (human-readable action summaries, risk/status
badges, duration, inline error preview).

Also added /api/v1/activity/session/{id} + a collapsible SessionDigest
panel in the chat rail, answering "what did this session actually do"
(executions by status, entities touched, knowledge written) — the
missing piece for proactive outcome reporting to be visible in the UI,
not just in the chat transcript.

+   the operator has approved your plan, you can execute all the steps:
+   install packages, edit configs, start services, etc. — no need to stop and
+   re-ask for each step.
+3. `read_only` commands always auto-run (no approval needed, no window).
+4. `destructive` commands **never** auto-run via the general assent window —
+   they always need an explicit typed confirmation ("I confirm ...") or the
+   operator clicking Approve on a card that says DESTRUCTIVE.

+   ONE target — further destructive commands against the SAME target auto-run
+   without asking again. This exists for multi-step destructive recovery
+   (e.g. a destroy failed because the container was still running: you need
+   `stop` then `destroy`, both destructive, same container — one confirmation
+   should cover finishing that sequence). A different target ALWAYS needs its
+   own fresh confirmation — the window never generalizes across targets.
+
+**Your job after approval:** carry out the full plan. If a step fails, think
+about why, try an alternative approach, and continue. Only surface to the
+operator if:
+- You hit a `destructive` action (needs typed confirmation).
+- You're genuinely stuck (tried reasonable alternatives, none worked).
+- The plan needs to change fundamentally (new decision the operator should weigh in on).
+
+Do NOT stop after every step waiting for "continue". The operator approved
+the plan — execute it end to end.
+
+**Automatic continuation — you are re-invoked when async steps finish.** Some
+steps (`pct_create`, `apt_upgrade`) run asynchronously: the tool returns
+"execution &lt;id&gt; running" immediately, and the actual work (which can take
+minutes) finishes later. **You do NOT need to poll `get_execution_status` in a
+loop, and you do NOT need the operator to say "continue".** When such a step
+finishes, the system automatically re-invokes you with a
+`[System: execution &lt;id&gt; finished with status=…]` note carrying the result.
+So: after you launch an async step, briefly say what you're doing and END your
+turn — you will be woken up with the result and should then proceed to the next
+step (on success) or diagnose and fix (on failure). Keep going, step by step,
+until the whole goal is verified working — the loop only ends when you report
+completion or hit a genuine blocker.
+
+**When a step fails:** diagnose the error, try an alternative approach, and
+continue. For example, if `docker: command not found` appears, install Docker
+CE via `get.docker.com` and retry. If a package is missing, install it. If a
+port is busy, find a free one. Only surface to the operator if you've tried
+reasonable alternatives and none worked. An error in one step is not a reason
+to stop the entire turn — it's a reason to try a different approach.
+
+**Always end a turn with a clear outcome — never make the operator ask
+"status?".** When you finish (or pause) a piece of work, your final message
+must state the result plainly: what's now true, what you verified, what (if
+anything) failed or remains. Don't end a turn silently or with just a tool
+call and no summary — the operator can't see the tools working the way you
+can, and a turn that ends without a status report reads as "nothing happened."
+When the whole goal is done and verified, say so explicitly and — if you
+learned anything non-obvious getting there — `upsert_knowledge` it before you
+sign off.

+# 2026-07-10 — Autonomous plan execution: close the observation gap
+
+**Status:** Planned
+
+## The real problem (not the one we kept fixing)
+
+Operator, verbatim: *"the agent seems to stop when it encounters the first error,
+it does not recover from it… my goal is that the agent can do anything once a
+plan has been approved."*
+
+We have patched ~10 individual failure modes (DNS, gateway, sshExec timeout,
+substring bug, slug collisions, docker CLI, assent window…). Every one was real.
+None fixed the thing the operator keeps hitting, because they all fixed
+**individual commands** — and the problem is the **loop**, not the commands.
+
+## Root cause: the agent never sees the result of the thing it started
+
+The agent runs in discrete request→response turns. Provisioning executions are
+**asynchronous**: `request_execution(pct_create)` queues an execution, fires the
+real SSH work in a **goroutine** (`go executeApprovedViaAPI(...)`,
+[internal/mcp/server.go](../internal/mcp/server.go)), and returns
+*"provisioning now"* immediately. The multi-minute result lands in the DB
+**after the agent's turn has already ended.**
+
+So the agent literally is not running when the error happens. It cannot react to
+a failure it never observes. The only way the result re-enters the agent's
+reasoning is if a human types "continue" to start a new turn — **the human is the
+event loop.** Read the failing session
+(`7c25edaa`, 18 messages): the operator typed "continue" / "continue?" / "??" /
+"proceed" **eight times**, each one just ticking the agent forward one async step.
+The agent *was* recovering (it correctly diagnosed the docker-CLI issue and
+proposed fixes) — it simply could not proceed one step without a human tick.
+
+Two concrete asymmetries prove the diagnosis:
+
+1. **`run` is synchronous, `pct_create` is async.** Inside an assent window, the
+   general `run` tool executes the command inline and returns stdout/exit-status
+   to the agent ([server.go](../internal/mcp/server.go) ~L514) — the agent *sees*
+   the result and can continue. `pct_create` in the same window auto-approves and
+   then `go`-routines the work — the agent sees nothing. The failure-prone path
+   is the unobservable one.
+2. **`pct_create` is monolithic and all-or-nothing.** It does create + apt +
+   docker + post_install + verify in one SSH call. Even if it were synchronous,
+   the agent could only see "the whole thing failed at some point," not step 3 of
+   6 — so it can't surgically fix step 3 and resume. Recovery *requires*
+   intermediate observation.
+
+Secondary (real but downstream): "continue" is **not** an assent word
+([cmd/nomos/assent.go](../cmd/nomos/assent.go)), so in that session the assent
+window never even opened — every step stayed gated, compounding the ticking.
+
+## The reframe: Nomos should work like a coding agent
+
+A coding agent (Claude Code) runs a command, **sees the output**, runs the next,
+fixes errors inline, all in one continuous session — it does not stop and ask a
+human to forward it after each command. That is exactly "do anything once the
+plan is approved." The homelab agent needs the same loop:
+
+> approve the plan → agent runs step → **observes result** → runs next step / on
+> failure diagnoses + adapts + retries → … → verifies goal met → reports.
+
+The machinery for this **already exists** in the `run` tool (synchronous,
+observable, auto-executing within an assent window). Provisioning just doesn't
+use it — it uses a black box. The fix is to make the whole system consistent
+with the model `run` already embodies.
+
+## Target architecture
+
+### 1. One observable primitive; retire the async black box
+
+- Everything the agent does — including provisioning — is a sequence of
+  **synchronous `run` calls** whose real output (stdout, stderr, exit code)
+  returns inline. No goroutine hand-off for agent-initiated work.
+- **Decompose `pct_create`.** Keep a thin `pct_create` that only does the fast,
+  atomic container creation (create + start + register), returning synchronously.
+  Move package install / service setup / post_install / verify **out** into
+  agent-driven `run` steps. Now the agent observes each step and can fix a
+  failed one without redoing the container.
+- Net: the agent orchestrates `create → apt → install → configure → up → verify`,
+  seeing each result, exactly like a human operator at a shell.
+
+### 2. Approve the plan = an autonomy grant the agent executes to completion
+
+- The assent/autonomy window already exists. Make it robust:
+  - Opening it must not depend on a magic word list. "continue", "go", "do it",
+    "proceed", clicking Approve, or approving the first queued step should all
+    open/extend it. Safer: when the operator approves ANY step of a plan, treat
+    that as opening the window for the rest of that plan.
+  - Within the window: read-only + config_mutation `run` steps execute inline,
+    no re-prompt. **Destructive still stops** for typed confirmation — but a
+    destructive step *described in the approved plan* can be pre-authorized so
+    the agent isn't blocked mid-flow on something already shown and approved.
+- The window is the scope boundary: "you may do what the plan needs on this
+  target; you may not wander outside it."
+
+### 3. The agent persists through errors (prompt + loop)
+
+- SOUL: "You are the executor of the approved plan. Run it step by step,
+  observing each result. **On failure, do not stop and hand back — diagnose
+  (read logs / inspect state), form a hypothesis, fix it, and retry or take an
+  alternative path.** Continue until the goal is verified working or you are
+  genuinely blocked (you need information only the operator has, or a step
+  exceeds the approved scope). Never end a turn with a half-finished plan just
+  because one command failed."
+- `maxIterations` sized for a full provision-with-recovery (raise 25 → ~40) and
+  count observation/read-only steps cheaply so recovery attempts aren't starved.
+
+### 4. Long-running steps: keep the turn alive, or auto-continue
+
+A synchronous `apt install` is ~1–2 min; a full stack up is longer. Options,
+in preference order:
+- **A (simplest, ship first):** synchronous `run` with the existing 10-min cap;
+  the streaming turn stays open (the chat UI already holds the SSE). Emit
+  progress events so the operator sees liveness (already built — elapsed timer).
+- **B (for very long ops):** event-driven auto-continuation — when an async
+  execution tied to an active plan completes, a worker **re-invokes Nomos**
+  automatically with the result (the system becomes the event loop, not the
+  human). More plumbing; do only if A's long turns prove problematic.
+
+## Why this is the root fix, not another patch
+
+Every prior fix made an individual command more likely to succeed. This makes
+the agent able to **notice and respond when one doesn't** — which is the only
+thing that generalizes to "do anything," because "anything" always includes
+"the first thing didn't work." You cannot enumerate every failure mode of an
+unbounded action space; you can give the agent a loop that observes and adapts.
+
+## Implementation order
+
+1. **Make provisioning observable**: decompose `pct_create` into a fast atomic
+   create + agent-orchestrated `run` steps for install/config/verify. (Biggest
+   single win — removes the async black box from the failure-prone path.)
+2. **Robust window open**: any approval / any forward-assent opens/extends it;
+   pre-authorize plan-described destructive steps.
+3. **SOUL persist-through-errors** framing + `maxIterations` bump.
+4. Verify end-to-end (below). Only then consider **B** (auto-continuation).
+
+## Verification
+
+- Re-run the exact TypeType deploy. Expected: operator approves the plan **once**;
+  the agent then creates the container, installs docker (recovering from the
+  Debian docker.io-CLI gap on its own by falling back to get.docker.com), brings
+  up the stack, hits a transient error (e.g. Docker Hub 500), **retries on its
+  own**, verifies `:8082` responds, and reports success — **with zero additional
+  "continue" ticks from the operator.**
+- Failure injection: point a step at a wrong path; confirm the agent reads the
+  error, adapts, and continues rather than ending the turn.
+
+## Open questions
+
+- **Scope of an autonomy window**: per-plan, per-target, time-boxed (30 min now)?
+  What exactly may the agent do inside it without asking again?
+- **Pre-authorized destructive steps**: allow a plan to include a named
+  destructive step (e.g. "destroy the half-provisioned CT and redo") that the
+  agent may execute during recovery without a fresh typed confirmation, since
+  the plan approval covered it? Or always re-confirm destructive, accepting the
+  interruption?
+- **A vs B**: is a single 5–10 min streaming turn acceptable, or do we need
+  event-driven auto-continuation from the start?
