refactor: ci-debug to lib, rewrite README

- Moved ci-debug.sh from dev/ to lib/ (shared utility)
- README: fixed supervisor description (all alerts go to claude)
- README: replaced implementation details with actual design principles

-## How It Works
+## Design Principles
 
-### Dev Agent (Pull System)
-1. `dev-poll.sh` scans `backlog`-labeled issues
-2. Checks if all dependencies are merged into master
-3. Picks the first ready issue, spawns `dev-agent.sh`
-4. Agent: creates worktree → `claude -p` implements → commits → pushes → creates PR
-5. Waits for CI. If CI fails: feeds errors back to claude (max 2 attempts per phase)
-6. Waits for review. If REQUEST_CHANGES: feeds review back to claude
-7. On APPROVE: merges PR, cleans up, closes issue
-
-### Review Agent
-1. `review-poll.sh` finds open PRs with passing CI and no review
-2. Spawns `review-pr.sh` which runs `claude -p` to review the diff
-3. Posts structured review comment with verdict (APPROVE / REQUEST_CHANGES / DISCUSS)
-4. Creates follow-up issues for pre-existing bugs found during review
-
-### Factory Supervisor
-1. `factory-poll.sh` runs pure bash checks every 10 minutes:
-   - CI: stuck or failing pipelines
-   - PRs: derailed (CI fail + no activity)
-   - Dev-agent: alive and making progress
-   - Git: clean state on master
-   - Infra: RAM, swap, disk, Anvil health
-   - Review: unreviewed PRs with passing CI
-2. Auto-fixes simple issues (restart Anvil, retrigger CI)
-3. Escalates complex issues via openclaw system event
+- **Bash for checks, AI for judgment** — health checks are shell scripts; AI is only invoked when something needs diagnosing or fixing
+- **Pull over push** — dev-agent derives readiness from merged dependencies, not labels or manual assignment
+- **Progressive disclosure** — the supervisor reads only the best-practices file relevant to the current problem, not all of them
+- **Self-improving** — when the AI fixes something new, it appends the lesson to best-practices for next time
