Codex 0b52093b36 K8s manifest hardening + new bluejay-infra-lint test project
Manifest hardening (per documented memories):
- apps/asterisk/deployment.yaml: dnsPolicy: None + explicit dnsConfig
  with ndots:2 to prevent CoreDNS *.iamworkin.lan template from
  hijacking external egress (downloads.asterisk.org).
- apps/fc-llm-bridge/fc-llm-bridge.yaml: same dnsConfig pattern for
  api.anthropic.com egress.
- apps/fc-ttsreader/fc-ttsreader.yaml: same dnsConfig pattern for
  huggingface.co model seeding.
- apps/fc-messageboard/fc-messageboard.yaml: tcpSocket probes
  (replacing httpGet /health) per "Probes against /health 404 when
  app has global auth middleware".
- apps/fc-signalcontrol/fc-signalcontrol.yaml: same tcpSocket probe
  fix.

New lint project:
- tests/bluejay-infra-lint/BluejayInfraLint.Tests.csproj — local-first
  lint test sweep for the recurring K8s gotchas in the fleet.
- tests/bluejay-infra-lint/FleetManifestLintTests.cs — 7 lint tests
  covering tcpSocket probes, dnsConfig presence on egress-heavy pods,
  IngressRoute/Service namespace alignment, image pull policy, etc.
- tests/bluejay-infra-lint/conftest.dev/ — matching conftest policies
  for environments with conftest/opa.
- .gitignore — adds bin/ + obj/ + DS_Store/swp.

README.md adds a "Local manifest lint" section with the canonical
test command, plus 4 new gotcha entries (IngressRoute namespace
split, public read-only host method allowlists, Traefik VIP netpol
backend ports, auth-safe probes).

Tests: 7 / 7 lint tests passed.
