refactor: rename factory/ → supervisor/, factory-poll → supervisor-poll

The supervisor agent was confusingly named "factory" (same as the
project). Rename directory, script, log, lock, status, and escalation
files. Update all references across scripts and docs.

FACTORY_ROOT env var unchanged (refers to project root, not agent).

+# CI Best Practices
+
+## Environment
+- Woodpecker CI at localhost:8000 (Docker backend)
+- Postgres DB: use `wpdb` helper from env.sh
+- Woodpecker API: use `woodpecker_api` helper from env.sh
+- Example (harb): CI images pre-built at `registry.niovi.voyage/harb/*:latest`
+
+## Safe Fixes
+- Retrigger CI: push empty commit to PR branch
+  ```bash
+  cd /tmp/${PROJECT_NAME}-worktree-<issue> && git commit --allow-empty -m "ci: retrigger" --no-verify && git push origin <branch> --force
+  ```
+- Restart woodpecker-agent: `sudo systemctl restart woodpecker-agent`
+- View pipeline status: `wpdb -c "SELECT number, status FROM pipelines WHERE repo_id=$WOODPECKER_REPO_ID ORDER BY number DESC LIMIT 5;"`
+- View failed steps: `bash ${FACTORY_ROOT}/lib/ci-debug.sh failures <pipeline-number>`
+- View step logs: `bash ${FACTORY_ROOT}/lib/ci-debug.sh logs <pipeline-number> <step-name>`
+
+## Dangerous (escalate)
+- Restarting woodpecker-server (drops all running pipelines)
+- Modifying pipeline configs in `.woodpecker/` directory
+
+## Known Issues
+- Codeberg rate-limits SSH clones. `git` step fails with exit 128. Retrigger usually works.
+- `log_entries` table grows fast (was 5.6GB once). Truncate periodically.
+- Example (harb): Running CI + harb stack = 14+ containers on 8GB. Memory pressure is real.
+- CI images take hours to rebuild. Never run `docker system prune -a`.
+
+## Lessons Learned
+- Exit code 128 on git step = Codeberg rate limit, not a code problem. Retrigger.
+- Exit code 137 = OOM kill. Check memory, kill stale processes, retrigger.
+- `node-quality` step fails on eslint/typescript errors — these need code fixes, not CI fixes.

+### Example (harb): FEE_DEST address must match DeployLocal.sol
+When DeployLocal.sol changes the feeDest address, bootstrap-common.sh must also be updated.
+Current feeDest = keccak256('harb.local.feeDest') = 0x8A9145E1Ea4C4d7FB08cF1011c8ac1F0e10F9383.
+Symptom: bootstrap step exits 1 after 'Granting recenter access to deployer' with no error — setRecenterAccess reverts because wrong address is impersonated.
+
+### Example (harb): keccak-derived FEE_DEST requires anvil_setBalance before impersonation
+When FEE_DEST is a keccak-derived address (e.g. keccak256('harb.local.feeDest')), it has zero ETH balance. Any function that calls `anvil_impersonateAccount` then `cast send --from $FEE_DEST --unlocked` will fail silently (output redirected to LOG_FILE) but exit 1 due to gas deduction failure. Fix: add `cast rpc anvil_setBalance "$FEE_DEST" "0xDE0B6B3A7640000"` before impersonation. Applied in both bootstrap-common.sh and red-team.sh.
