Rebrand: TeamClaw -> Clawmates (clawmates.work)

Full-depth rename per the approved plan; the 'claw' product vocabulary
(claws, /claws routes, clawId, Claw Chat) stays — it is now the brand.

- Display brand: Clawmates (manifest, titles, hero, login/rail logo
  'clawmates'); default host app.clawmates.work; registry
  ghcr.io/clawmates
- Crates tc-* -> cm-* (16 crates + all imports); binaries
  clawmates-server/broker/bundler; images clawmates/*; env prefix
  CLAWMATES_* (+ CM_TEST_DATABASE_URL / CM_LIVE_LLM); config
  clawmates.toml; helm chart deploy/helm/clawmates with clawmates-*
  resources; db names clawmates*; sockets /run/clawmates; cookie
  cm_session; kind cluster clawmates-test; seccomp node profile
  clawmates-agent-profile.json
- All 9 Playwright brand assertions updated in lockstep; historical
  spec document left untouched as the only remaining 'TeamClaw'
- Local env migrated: dev pg clawmates-dev-pg/clawmates_dev, shared
  test server clawmates-test-pg, kind cluster recreated with image +
  profile, compose images rebuilt under clawmates/*

Verified end to end: 161 Rust + 68 frontend tests, 29 Playwright
journeys, 4 live kind tests, helm/install/LOC/placeholder gates, and
the clean-room install rehearsal serving the clawmates login page from
a signed bundle of the rebuilt images.
