Jon Chery fc94326b0e feat(P00): deprecation sweep + bash tooling gate + render contract + doc banners (v0.9 P00)
P00 — Re-architecture Foundation (deprecation/migration/test-infra/persona/docs).

Deprecation sweep (REQ-068, REQ-072, REQ-089):
- Add // Deprecated: doc comments to internal/daemon (R-001), internal/transport
  (REQ-073), internal/security/ca.go+csr.go (D-101/REQ-076), internal/engine/
  dispatcher.go+peer.go (CLI-side scheduler), internal/cli/daemon.go.
- orca daemon emits slog.Warn deprecation banner on every run (ungated); fires
  R-001 + v0.10-P05 drain-and-stop + v0.10-P14 deletion.
- orca cert and orca node join (mTLS path) emit deprecation warnings; proxmox
  SSH path (the v0.9 replacement) does not warn.
- Add --no-deprecation-warnings global flag on root command (PersistentPreRunE)
  for orca upgrade migrations.
- 12 new daemon/cert/node deprecation tests in internal/cli/daemon_test.go
  (cli coverage 81.9%, warnDeprecated 100%).
- Add DEPRECATED banners to v0.8 sections of ARCHITECTURE.md (verified the
  v0.9 supersession section + Supersession Table from prior turn are present).

Bash tooling gate (grill C-06, C-15, C-16, C-17, C-18):
- scripts/tests/test_helper.bash + example_test.bash — bats framework + helpers.
- scripts/lib/orca-log.sh — slog-compatible JSON logging to syslog (C-17).
- scripts/orca-verify-render.sh — render-contract validator skeleton (C-16).
- scripts/tests/orca-log_test.bash + orca-verify-render_test.bash — 20 bats
  tests total (happy + failure paths per C-15).
- .shellcheckrc — project shellcheck config.
- Makefile: test-bash + lint-bash targets (graceful skip if tools missing);
  wired into test + lint targets.
- internal/emit/contract.go + contract_test.go — versioned JSON render
  contract (orca.emit/v1) between Go emitters and bash appliers (C-16).
- .ciagent/BASH_CAPABILITY_MAP_v0.9.md — maps shipped internal/transport
  capabilities to bash-side equivalents or accepted drops (C-18).
- D-186 recorded in PROJECT.md: bash exempt from Go coverage gate; compensating
  control is bats + shellcheck + shfmt (C-06).

verify-reqs: 90 requirements consistent. Build/test/lint/fmt all green.
20 bats tests pass. Go tests pass. No v0.8 code deleted — only marked deprecated
(deletion deferred to v0.10-P14 per REQ-090 dual-write window).
