ci(workflows): add job-level timeout-minutes (Hypatia workflow_audit)

Clears the Hypatia `missing_timeout_minutes` (workflow_audit, medium)
findings by giving every normal job a job-level timeout-minutes —
23 jobs across 11 workflows. Generous upper bounds that cap runaway
jobs without affecting normal runs:

  boj-build 10, instant-sync 10, dogfood-gate 15, rhodibot 15,
  scorecard-enforcer 15, codeql 30, casket-pages 30, hypatia-scan 30,
  release 30, static-analysis-gate 30, cross-platform 30

Reusable-workflow caller jobs (governance, mirror, scorecard,
secret-scanner) are intentionally untouched: GitHub rejects
timeout-minutes on a job that calls a reusable workflow via `uses:` —
that timeout belongs in the called workflow (hyperpolymath/standards),
which is out of scope for this repo.
