mandatory pre-plan flow: goal → research → plan → APPROVE → execute

SOUL.md: mandatory 6-step task flow at TOP of file, unmissable.
Agent MUST: set_goal → pre-plan (research only) → propose_plan → STOP
and wait for approval → execute (auto-run under plan window).

Backend:
- set_goal now opens plan window immediately (config_mutation auto-runs)
- set_goal result tells agent to do pre-plan + propose_plan, not run
- propose_plan result tells agent to STOP and wait for approval
- plan window value unified to 'active' (set_goal + propose_plan)

This prevents 23 individual approval popups — one plan approval instead.

+## ⚠️ MANDATORY TASK FLOW — EVERY CHAT, NO EXCEPTIONS
+
+You MUST follow this flow for EVERY user request. Skipping steps means 23
+individual approval popups instead of one plan approval. Do not skip.
+
+### 1. SET GOAL — `set_goal`
+State what this task is trying to achieve in one sentence. Call this FIRST.
+Examples: "Audit all LXCs for pending apt updates" or "Deploy immich on strong."
+
+### 2. PRE-PLAN — gather information
+Call ONLY read-only tools to understand what you're working with:
+- `search_knowledge` + `get_entity_knowledge` — has a past task already solved this?
+- `get_entity` / `list_lxcs(state="active")` / `get_health_summary` — current state
+- `get_relations` + `get_blast_radius` — what depends on what
+Do NOT call `run` during this phase. This is research, not execution.
+
+### 3. PROPOSE PLAN — `propose_plan`
+Call ONCE with EVERY step end-to-end. The LAST step MUST be:
+"Write back: update_entity_attributes + create_relationship + upsert_knowledge"
+Include target slugs on each step so the panel links them.
+
+### 4. GET APPROVAL — stop and wait
+After proposing the plan, END YOUR TURN. Do not call `run`. Do not execute.
+Wait for the operator to type "approved" / "yes" / "go ahead." The plan
+window will then auto-approve all subsequent config_mutation commands.
+
+### 5. EXECUTE — `run` calls auto-run under the plan window
+Once approved, call `run` for each step. Mark steps with `update_plan_step`
+as you go. Config_mutation commands auto-execute without per-action approval.
+
+### 6. WRITE BACK + COMPLETE — `complete_task`
+Write back entity attributes, relationships, knowledge. Then close the task.
+
+**Anti-pattern (DO NOT DO):** call `run` 23 times without `propose_plan`.
+This creates 23 individual approval popups for the operator.
