fix(cv): isolate document parsing

Run untrusted document decoders in a secret-free, resource-bounded child process and terminate its process tree on deadline. Harden the production container and enforce parser and lint gates in CI.

 ### In progress
 
-- SEC-007 bounded document processing. Upload-facing parser dependencies are fixed and hash-locked; the sidecar now rejects signature mismatches, decompression/page/pixel/output excesses, the backend no longer retries PDF/DOCX/image parsing in-process, and unexpected parser details are sanitized. Child-process deadline/resource isolation and container controls remain.
+- No repository implementation package is currently in progress. SEC-006/SEC-007 await a running Linux Docker daemon for image/runtime proof; production activation remains separately gated.

 - Playwright: 8/10 passed on the first complete run; both failures were ambiguous selectors in the newly responsive Career selector, not product failures. Both corrected focused regressions now pass (2/2); final full rerun remains in the end-of-batch gate.
 - Manual desktop browser review: webpack development server rendered the new Career navigation and Overview correctly in dark mode; API-dependent profile status remained unavailable because the backend was not running for that isolated UI review.

 - **Completed work packages:** None are `DONE`; all repository security/AI packages still have applicable browser, provider and/or production gates.

 - **Production-verified work:** None.
 - **Blocked work:** PROD-001/003/004 and REL-001 require network/backup/model/deployment authority and unfinished dependencies. Real provider and live deletion/restore checks remain gated; DEP-001 awaits approved merge/live verification.
 - **Deferred work:** None. Conditional multi-replica coordination, model deletion, realtime operation delivery and unrelated production changes remain outside current packages.
 - **Immediate order:** all sixteen immediate repository items are complete locally, including the original UI/release queue plus SEC-009 cache/tombstone safety, worker restart clocks, universal AI accounting, email-token/Stripe lifecycle tests, exhaustive Job email selectors, the repaired migration chain, CV/public-edge hardening and measured admin/mail scaling. PROD-001 read-only evidence and the PROD-003 plan-only harness are also complete. The final audit is checking tooling/documentation before declaring only external blockers remain.

 - **Deployment status:** Gitea pull-request run 609 passed the complete CI job in 4m20s. Deploy was intentionally skipped because the workflow deploys only a `push` to `main`; live remains unchanged. No merge/deployment was performed directly, no production migrations were run and the AI operation worker remains disabled by default.
 - **Production status:** State unchanged. Sanitized read-only SSH inventory was performed; no logs, prompts, private rows/content or secret values were read, and no provider/model call, model pull, service restart, file/config change, backup, restore, migration or deployment occurred. It confirmed all-interface Ollama/frontend listeners and stale database-only backups as rollout blockers.
 - **Known regressions:** None found by automated/local browser checks. Jest still needs `--forceExit` and reports its existing open-handle notice. Email-provider/send tests are fake/local only; real delivery is not claimed. Current MAIL browser evidence is 1280×720 only because the browser surface could not resize or perform native Tab traversal. Interrupted attempts are aged after 15 minutes and notified without retry; the five-minute scan is unmeasured on a large ledger. The direct clean EF-only SQLite defect and synchronous AI accounting gap are closed; migration/reconciler dual ownership remains architectural debt.
