Gergo Magyar e6f181493c fix(workers): apply code-review fixes (12 findings)
Walks through every finding from ce-code-review run
20260519-094648-3549cf5e. All 12 picked Apply.

Critical:
- F1 — Layer 5 cumulative-timeout exhaustion no longer silently drops
  the rest of the job. `requeueRemainder` is now invoked before
  `handleWorkerDeath` in both Layer 5 and singleton-final-fail give-up
  paths so non-quarantined items get re-tried by another worker.
- F2 — idle-timer recovery overhaul. `!shouldContinue` branch no
  longer calls `replaceWorker` (double-spawn race with the
  `handleWorkerDeath` inside `requeueAfterTimeout`). `shouldContinue`
  branch now enforces `maxRespawnsPerSlot` before respawning, closing
  the budget-bypass for the timeout-retry path. Also fixes premature
  `maybeDone` by simplifying the bookkeeping.
- F3 — `requeueRemainder` no longer pre-charges `cumulativeTimeoutMs`
  by `job.timeoutMs`. The death itself consumed no budget, so the
  next `requeueAfterTimeout` was double-billing the first attempt.
- F4 — `WorkerPool.getQuarantinedPaths` is now optional on the
  interface, matching the defensive `?.()` call site and the existing
  mocks. Removes the contract-vs-callsite contradiction.
- F5 — per-job unattributed-death tracking. When a worker dies with
  no exclusion attribution, `requeueRemainder` tracks death count per
  `startIndex`. First time: re-queue intact. Second time: quarantine
  items[0] as best guess, or drop the job entirely when items lack
  paths. Bounds the death loop the original design admitted to.
- F6 — per-slot consecutive-failure counter. Replaces the pool-wide
  scalar so a chronically-failing slot trips the breaker on its own
  streak instead of being masked by another slot's successes.

Smaller:
- F7 — exhaustiveness `never` check on `WorkerOutgoingMessage` union.
- F8 — recursive `runWorker` on fully-quarantined jobs converted to
  a while-loop.
- F9 — `tripBreaker` calls `reject(err)` BEFORE awaiting
  `worker.terminate()`. A stuck terminate no longer blocks the caller.
- F10 — `parsing-processor.ts` quarantine log de-duplicates per pool
  instance via a `WeakMap`. Only newly-quarantined paths are logged
  in each chunk; the per-chunk count still surfaces via progress.
- F11 — extract `firstPath` local in `requeueAfterTimeout`; eliminates
  double `itemPath` call and the `unknown as string` cast.

Tests (F12, 6 new):
- crash-error event path (errorHandler).
- F5 drop-branch coverage via items without `.path`.
- Common-case unattributable crash falling back to items[0] heuristic.
- `replaceWorker` startup failure (workerFactory emits 'exit' before
  'online').
- All-slots-dropped breaker trip.
- `GITNEXUS_WORKER_MAX_CUMULATIVE_TIMEOUT_MS` env override.

Residual gap (deferred): no unit test exercises the Layer 5
cumulative-budget runtime path — requires fake-timer interleaving
with FakeWorker that's too brittle for this iteration. Tracked.
