Bigdei Kodesh: HTTP API layer — four garments for four access tiers

Shemot 28:2 — V'asita vigdei kodesh l'Aharon achicha,
l'khavod ul'tifaret.

The builder makes the garments. The kohen wears them.

Four access tiers (Operations spec §1.1):
- Pe'ah (GET/POST /peah/ask) — public, no auth, no tracking.
  The stranger is safe to approach.
- Courtyard (POST /courtyard/offering) — Bearer token auth,
  offering types: shelamim, olah, chatat, minchah
- Chatzer (POST /chatzer/sanhedrin) — Sanhedrin deliberation,
  returns majority/minority with preserved dissent
- Kodesh (GET /kodesh/health, /kodesh/status) — operator interface,
  health checks for K8s liveness/readiness probes

Error format follows chatat protocol (Operations spec §1.2):
  KIYOR_* (422), SHABBAT (503), MANNA_DEPLETED (503),
  CLOUD_MOVING (503), HALT_* (503), UNAUTHORIZED (401)

Implementation:
- Plug.Router with Bandit HTTP server
- Added to supervision tree via maybe_add_http_server
- Checks system availability (Shabbat, halt) before processing
- Health check reads L1 integrity, cloud, manna, halt monitor
- Status shows all component states, signal count, refuge list
- 16 API tests covering all four tiers + error format

All 235 Elixir + 19 L3 + 195 Prolog + 33 Haskell = 463+ tests, 0 failures
