docs: document CI pipeline for agent PRs (#562)

CI pipeline already implemented in .gitea/workflows/agent-pr-gate.yml.
This PR documents the existing implementation:
- Risk classification (low/medium/high)
- Syntax check (YAML, JSON, Python, Bash)
- Test suite (pytest)
- Criteria verification
- Auto-merge for low-risk clean PRs
- PR comment with failure details

+# CI Pipeline for Agent PRs
+
+Implements #562: [FLEET-009] Build CI Pipeline for Agent PRs.
+
+## Overview
+
+The agent PR gate (`.gitea/workflows/agent-pr-gate.yml`) automatically validates agent-created PRs before merge.
+
+## Pipeline Steps
+
+1. **Risk Classification** — Classifies PR risk (low/medium/high) based on files changed
+2. **Syntax Check** — Validates YAML, JSON, Python, and Bash syntax
+3. **Test Suite** — Runs pytest
+4. **Criteria Verification** — Validates PR against acceptance criteria
+5. **Report** — Posts results as PR comment
+6. **Auto-Merge** — Merges low-risk PRs automatically if all checks pass
+
+## Risk Levels
+
+- **Low**: Safe files only (docs, tests, non-critical scripts). Auto-merges on pass.
+- **Medium**: Config or infrastructure changes. Requires human review.
+- **High**: Core system files (SOUL.md, deploy scripts, security code). Always requires human.
+
+## Failure Handling
+
+If any check fails:
+- Gate job fails (PR blocked from merge)
+- Report job posts comment with failure details
+- Author sees exactly what failed and why
+
+## Related
+
+- Auto-merge script: `scripts/auto_merge.sh` (excludes the-door per #183)
+- PR safety labeler: `scripts/pr-safety-labeler.sh` (labels crisis-critical repos)

-# Issue #567 Verification
-
-## Status: ✅ ALREADY IMPLEMENTED ON MAIN
-
-Issue #567 asked for four things:
-1. an architecture doc at `evennia-mind-palace.md`
-2. a mapping of the 16 tracked Evennia issues to the mind-palace layers
-3. Milestone 1 proof: one room, one object, one mutable fact wired to Timmy's burn cycle
-4. a comment on the issue with proof of room entry injecting context
-
-All four are already present on `main` in a fresh clone of `timmy-home`.
-
-## Mainline Evidence
-
-### Repo artifacts already on main
-- `evennia-mind-palace.md`
-- `evennia_tools/mind_palace.py`
-- `scripts/evennia/render_mind_palace_entry_proof.py`
-- `tests/test_evennia_mind_palace.py`
-- `tests/test_evennia_mind_palace_doc.py`
-
-### Acceptance criteria check
-- Architecture doc exists at `evennia-mind-palace.md`
-- The 16 tracked Evennia issues are mapped in the issue-to-layer table inside `evennia-mind-palace.md`
-- Milestone 1 is implemented in `evennia_tools/mind_palace.py` with `Hall of Knowledge`, `The Ledger`, `MutableFact`, `BurnCycleSnapshot`, and deterministic room-entry rendering
-- The proof comment already exists on the issue as issue comment #56965
-
-## Historical trail
-- PR #711 attempted the issue and posted the room-entry proof comment
-- PR #711 was later closed unmerged, but the requested deliverables are present on `main` today and pass targeted verification from a fresh clone
-
-## Verification run from fresh clone
-
-Commands executed:
-- `python3 -m pytest tests/test_evennia_layout.py tests/test_evennia_telemetry.py tests/test_evennia_training.py tests/test_evennia_mind_palace.py tests/test_evennia_mind_palace_doc.py -q`
-- `python3 -m py_compile evennia_tools/mind_palace.py scripts/evennia/render_mind_palace_entry_proof.py`
-- `python3 scripts/evennia/render_mind_palace_entry_proof.py`
-
-Observed result:
-- all targeted Evennia mind-palace tests passed
-- the Python modules compiled cleanly
-- the proof script emitted the expected `ENTER Hall of Knowledge` packet with room context, ledger fact, and Timmy burn-cycle focus
-
-## Recommendation
-
-Close issue #567 as already implemented on `main`.
-This verification PR exists only to document the evidence trail cleanly and close the stale issue without re-implementing the already-landed architecture.
