feat: pct_create action, ToolCallGroup collapse+animation, inline chat approval

- Add pct_create to request_execution (MCP) and executeApprovedAction (httpapi)
  Parses JSON config: vmid, hostname, cores, memory, disk_gb, ip, gw, storage,
  template, privileged, nesting, mounts, nameserver, searchdomain. Creates
  entity (state=provisioning), hosts relationship, entity_status on success.
  Fixes action string parsing to use Index instead of SplitN (colons in JSON).

- Rewrite ToolCallGroup.svelte: bits-ui Collapsible replaces native <details>.
  Collapsed by default. Animated header shows live tool count + running tool
  name while streaming. Auto-expands during streaming, auto-collapses on done.

- Add InlineApproval component: parses 'execution UUID queued' from agent
  response, renders Approve/Deny buttons inline in chat, calls decideApproval.

- Document pct_create in nomos/SOUL.md with params, risk class, and approval flow.

- Add session-review skill at .agents/skills/session-review/SKILL.md.

- Add plan: 2026-07-09-session-execution-and-ux-fixes.md.

+description: "Examine a Nomos chat session, compare the user's objective with the actual outcome, identify causes of failure (missing tools, excessive tool calls, blocked actions, model behavior), and propose concrete fixes."
+risk_class: reversible_low
+inputs: [session_id]
+---
+# Session review
+
+Analyze Nomos chat sessions from the live database, diff objectives
+against outcomes, and propose fixes.
+
+## 1. Retrieve session data
+
+```bash
+# List recent sessions
+curl -s http://localhost:8092/sessions | jq '.sessions[:5]'
+
+# Fetch one session with messages
+curl -s http://localhost:8092/sessions/{session_id} | jq .
+```
+
+## 2. Classify the session
+
+For each session determine:
+
+| Dimension | Check |
+|-----------|-------|
+| Objective | What was the user trying to accomplish? |
+| Outcome | Was it achieved? (read final assistant text) |
+| Tool calls | Count, unique tools, redundancy (e.g., N+1 fan-out) |
+| Blockers | Missing action? Missing tool? Model refusal? Empty response? |
+| User frustration | Did the user need to clarify/correct/repeat? |
+| Message sizes | Content blob sizes — truncation needed? |
+
+## 3. Key failure signatures
+
+| Signature | Root cause | Fix |
+|-----------|-----------|-----|
+| Agent: "I can't run X — only supports Y" | Missing action in `request_execution` | Add action in `internal/mcp/server.go` |
+| Agent: "No local knowledge on that" + no web tool | Missing `http_get` / web fetch MCP tool | Add MCP tool |
+| Empty assistant bubble (text="", no tools) | Model returned blank completion | Retry + error surfacing |
+| Non-English boilerplate refusal | Flash-tier model degradation | Response quality guard |
+| >30 tool calls per turn, same tool repeated | N+1 fan-out instead of bulk tool | Enrich bulk tools + tighten SOUL.md |
+| Message >50KB in DB | Raw tool results persisted verbatim | Truncation in `store.go` |
+
+## 4. Extract patterns across sessions
+
+```bash
+# All sessions summary
+curl -s http://localhost:8092/sessions | jq -r '.sessions[] | "\(.id[:8]) \(.title[:80]) \(.created_at[:16])"'
+
+# Message count + tool count per session
+for id in $(curl -s http://localhost:8092/sessions | jq -r '.sessions[].id'); do
+  msgs=$(curl -s "http://localhost:8092/sessions/$id" | jq '.messages | length')
+  tools=$(curl -s "http://localhost:8092/sessions/$id" | jq '[.messages[].content.tool_calls | length] | add')
+  echo "$id $msgs msgs $tools tools"
+done
+```
+
+## 5. Output format
+
+```
+Session: {id[:8]} — "{title[:60]}"
+  Messages: {N} ({user}/{assistant})
+  Tool calls: {total} across {turns} turns
+  Top tools: {name:count, name:count, ...}
+  Objective: {one-line summary}
+  Outcome: ✅ / ❌ / ⚠️
+  Blockers: {list or "none"}
+  Fixes needed: {concrete actions}
+  Severity: blocker | friction | cosmetic

+Fix the hard blocker and UX issues found in the latest production Nomos session
+(`b9c5de7c-e0b5-424c-9149-9fd45b2e7011` — "deploy TypeType as an LXC on strong").
+The user asked Nomos to deploy an LXC; Nomos gathered data, proposed a plan, but
+at the final step ("run all yourself") said it *couldn't* — `request_execution`
+has no `pct_create` action. The user's objective was not achieved.
+
+## Session analysis
+
+10 messages (5 user / 5 assistant), 150 tool calls, zero LXC created.
+
+| Msg | Role | Tool calls | Top tools | Summary |
+|-----|------|-----------|-----------|---------|
+| 0 | user | 0 | — | "deploy TypeType on strong as LXC" |
+| 1 | assistant | 40 | get_entity(20), search_knowledge(12) | Fleet scan, entity detail per host/LXC |
+| 2 | user | 0 | — | "it's github.com/Priveetee/TypeType, use tube.hubris.network" |
+| 3 | assistant | 2 | search_knowledge(2) | MCP has no web fetch tool → couldn't read GitHub |
+| 4 | user | 0 | — | "I think you can figure out those" |
+| 5 | assistant | 60 | search_knowledge(32), request_execution(14) | Built the plan, tried provisioning, failed silently |
+| 6 | user | 0 | — | "connect to strong media disk, no youtube login, proceed" |
+| 7 | assistant | 44 | search_knowledge(10), get_entity(10), request_execution(8) | Full deployment plan laid out |
+| 8 | user | 0 | — | "run all yourself" |
+| 9 | assistant | 4 | request_execution(4) | **"I can't run pct create — only pct_exec, systemctl, restart, apt_upgrade"** — failure |
+
+## Findings
+
+### 1. HARD BLOCKER: `pct_create` missing from `request_execution`
+
+`request_execution` (`internal/mcp/server.go:264-376`) supports `restart`,
+`systemctl`, `pct_exec`, `apt_upgrade`. The actuator has `ProvisionLXC()`
+(`internal/actuator/actuator.go:209`) that calls `pct create` via SSH, but it
+is only wired into the auto-act signal pipeline — Nomos has no way to invoke
+it through MCP.
+
+Nomos's final response laid out the exact `pct create` command the operator
+needs to run manually on the Proxmox host. That's a dead end for the user, who
+expected the agent to execute from chat.
+
+**Fix:**
+- Add `pct_create` action to `request_execution` handler.
+- Wire it to the existing `ProvisionLXC()` function.
+- Classification: `config_mutation` — requires operator approval. Once approved
+  (from the Ops page or Matrix), the actuator picks it up and provisions the
+  LXC with the step callback reporting progress.
+- Alternatively (for the "run from chat" expectation): add a chat-level approval
+  flow — when Nomos proposes `request_execution` with `pct_create`, the frontend
+  renders an inline "Approve" button in the chat bubble. Operator clicks → it runs.
+  This is the UX the user described: "allow the agent to run things directly from
+  the chat I'm in."
+
+### 2. UI: ToolCallGroup expanded by default during streaming — no status animation
+
+`ToolCallGroup.svelte` uses `<details open>` when `active=true`. During a
+streaming turn with 40+ tool calls, the collapsed group fills the viewport
+with raw JSON. The summary header shows only a static icon and "N tools" text.
+
+**What happens now:**
+- Streaming starts → group opens and stays open → all tool results visible as raw JSON.
+- When streaming ends → auto-collapses. No animation.
+- Header shows `WrenchIcon` pulsing OR `CheckIcon` OR `XIcon` — but no live
+  running count, no per-tool status in the collapsed summary bar.
+
+**What should happen:**
+- Group starts **collapsed** by default. The summary header shows a live animated
+  status: "⠋ Running get_lxc_state (caddy)… [2/40 done]" with the active tool
+  name + a progress fraction, updating in real time.
+- When a tool completes, the header briefly reflects it ("✓ get_lxc_state (caddy)")
+  before moving to the next.
+- Clicking the summary expands the group with a smooth animated open/close
+  (replacing native `<details>` with bits-ui `Collapsible` + CSS transition).
+- On load from history (not streaming), always starts collapsed.
+
+**Fix:**
+- Replace `<details open>` with bits-ui `Collapsible` component (already in
+  `web/src/lib/components/ui/collapsible/`).
+- Add `animate-pulse` to the chevron icon during streaming (user sees motion).
+- Add a `statusText` derived that shows the in-progress tool name + count.
+- CSS animation: `Collapsible.Content` supports `forceMount` with transitions.
+
+### 3. No web-fetch tool → Nomos can't read GitHub READMEs
+
+Msg 3: Nomos needed to inspect `github.com/Priveetee/TypeType` to understand the
+stack. It used `search_knowledge` (DB FTS), which returned nothing because the
+repo isn't in the DB. The agent had no way to fetch external URLs.
+
+The MCP has 27 tools (21 listed in AGENTS.md + 6 more added since), but none
+for HTTP/web fetching. Nomos can only query the DB or execute SSH commands on
+existing hosts.
+
+This forced the human to provide context that should have been machine-read.
+
+**Fix options (non-blocking):**
+- Add an `http_get` MCP tool that returns sanitized body text (strip scripts,
+  truncate to 8KB). Rate-limited per-turn.
+- Or: add `web_fetch` as a first-class action in the MCP gateway itself, since
+  the gateway container already makes outbound HTTP calls to OpenRouter.
+
+### 4. Task: Bulk-tool awareness already in SOUL.md but not enough
+
+The SOUL.md already says "prefer `list_lxcs` over `get_lxc_state` for fleet-wide"
+(line 27-28). But msg 1 still made 40 calls. The issue:
+
+- `get_entity` was called 20 times (one per entity found by `list_entities`).
+  `list_entities` already returns all entities; the agent wanted per-entity
+  detail, which is redundant since `explain` or `get_state_snapshot` gives the
+  same info in one call.
+
+**Fix (already planned in `2026-07-09-chat-sessions-improvements.md` finding 3):**
+- Enrich `list_lxcs` with CPU/memory utilization so the model doesn't feel it
+  needs `get_lxc_state` per container.
+- Add `get_tools_summary` to SOUL.md preamble that lists each tool's intended
+  use and warns about N+1 call patterns.
+
+### 5. Skill gaps
+
+| Missing | Why | Where to add |
+|---------|-----|-------------|
+| `http_get` / `web_fetch` | Agent can't read external URLs | MCP tool in `internal/mcp/server.go` |
+| `session-review` skill | No way to learn from failed sessions | `.agents/skills/session-review/SKILL.md` |
+| `pct_create` action | Can't provision new LXCs from chat | `internal/mcp/server.go` + `internal/actuator/` |
+| `request_execution` approval from chat | Operator must switch to Ops page | Inline chat approval component |
+
+## Implementation order
+
+1. **Add `pct_create` to `request_execution`** (`internal/mcp/server.go`) —
+   hard blocker, needed for the session's objective.
+2. **ToolCallGroup: collapse by default + animated status header**
+   (`web/src/lib/components/ToolCallGroup.svelte`) — immediate UX win, the user
+   explicitly asked for this.
+3. **Inline chat approval for `request_execution`** — renders an "Approve"/"Deny"
+   button inside the chat when an execution is queued for approval. Lets the
+   operator approve from the same chat.
+4. **`session-review` local skill** — lives in `.agents/skills/`, loads when
+   examining chat sessions for failure patterns.
+5. **`http_get` MCP tool** — non-blocking but addresses a real gap seen in this
+   session.
+
+## Verification
+
+- Re-run the TypeType deploy prompt against the patched agent. Confirm:
+  - Agent proposes plan as before (keep plan-proposal behavior).
+  - When user says "run all", agent calls `request_execution(target=lxc:typetype,
+    action=pct_create, params=<json>)`.
+  - Approval fires → operator sees inline approval in chat → approves → LXC created.
+- ToolCallGroup: start a session that triggers 5+ tool calls. Confirm:
+  - Group starts collapsed.
+  - Summary header shows animated status: tool name + count updating in real time.
+  - Clicking expands smoothly.
+  - On session reload (history), stays collapsed.
+- Load `session-review` skill and ask it to analyze the TypeType failure session;
+  confirm it identifies the missing action as the root cause.
