v0.41.26.1 fix: lock-renewal cathedral — closes ~39 worker crashes/day (supersedes #1567)

Production worker daemons against Supabase / PgBouncer were crashing
~39 times/day with `unhandledRejection at renewLock`. PR #1567
proposed the right try/catch shape; this wave incorporates it and
closes the entire bug class (4 inside-review + 8 outside-voice
findings absorbed via 9 locked design decisions).

What's fixed:

- `setInterval(async () => await renewLock(...))` replaced with a
  sync wrapper around the new pure `runLockRenewalTick` function.
  No more unhandled rejections escaping the timer callback.
- Second crash vector closed: `.catch()` on the stored
  `executeJob(...).finally(...)` promise so failJob/completeJob
  throws during the same outage can't propagate to
  `process.on('unhandledRejection')`.
- Per-call `Promise.race` timeout (default `lockDuration/3`) bounds
  hung renewLock calls so the re-entrancy guard can't wedge
  indefinitely.
- Time-based abort (NOT count-based) so the worker releases its
  lock BEFORE another worker can reclaim. With the prior 3-strike
  count + 30s lockDuration, a 15s window let other workers race.
- Infrastructure aborts (`lock-renewal-failed`, `lock-lost`) don't
  burn job attempts — `executeJob`'s catch consults the exported
  `INFRASTRUCTURE_ABORT_REASONS` set and skips `failJob` so the
  stall detector reclaims cleanly.
- Universal grace-eviction: 30s force-evict safety net now fires
  for ANY abort reason, not just `job.timeout_ms`.

What's added:

- `src/core/minions/lock-renewal-tick.ts` (NEW): pure extracted
  state-machine function + env-knob resolver. Three operator-tunable
  knobs via env (max-failures-for-audit, call-timeout-ms,
  safety-margin-ms) with stderr-warn-once on bad input + default
  fallback.
- `src/core/audit/lock-renewal-audit.ts` (NEW): sibling of
  `batch-retry-audit.ts`. Four outcomes: failure /
  success_after_failure / gave_up / executeJob_rejected. JSONL at
  `~/.gbrain/audit/lock-renewal-YYYY-Www.jsonl`.
- `src/core/audit/redact-connection-info.ts` (NEW): shared privacy
  helper. Strips Postgres URLs, host=, user=, password=, IPv4 from
  error messages before they hit audit JSONL. Wired into BOTH the
  new lock-renewal audit AND the existing batch-retry audit
  (privacy backfill — same risk class).
- `scripts/check-worker-lock-renewal-shape.sh` (NEW): CI guard
  wired into `bun run verify`. Asserts the v0.41.22.1 bug pattern
  (`lockTimer = setInterval(async ...)`) stays absent AND the pure
  function call site survives refactors. Bug-pattern-specific so it
  doesn't fight legitimate refactors (codex C12).

Tests: 64 new cases across 5 new test files. 182 existing minion +
worker tests still pass. All hermetic — no PGLite, no real network,
no `mock.module`.

Plan + 9 decisions + codex outside-voice review at
~/.claude/plans/system-instruction-you-are-working-humming-nygaard.md

Closes #1567 (incorporates the contributor's try/catch shape; closes
the bug class structurally).

/**
* v0.41.22.2 — meta-test for scripts/check-worker-lock-renewal-shape.sh.
*
* Runs the CI guard against fixture worker.ts variants and asserts:
* 1. Good shape (the v0.41.22.2 final form) exits 0.
* 2. Bug pattern at the lock-renewal site (`lockTimer = setInterval(async ...)`)
* exits 1.
* 3. Missing call site (`runLockRenewalTick` not referenced) exits 1.
* 4. False-positive defense: `lockTimer = setInterval(syncCallback, ms)` with a
* named-ref second arg is allowed (NOT the bug pattern even if `async`
* appears later in the file in a different context).
*
* Uses the GBRAIN_LOCK_RENEWAL_SHAPE_TARGET env knob (built into the
* script) to swap the scanned file without git-mucking. Hermetic via
* per-test tempfiles.
