feat: make GEMINI_AUTH=oauth authenticate in Docker

OAuth cannot be done interactively in the headless container, so the login
must be seeded into the mounted ~/.gemini. Three problems are fixed:

- Mount fragility on the Windows Docker Desktop target: the creds mount
  defaulted to ${HOME}/.config/javis/gemini, but ${HOME} is often unset when
  compose runs outside a WSL shell, silently mounting the wrong dir. Default is
  now the project-local ./docker/gemini-oauth (cross-platform), GEMINI_OAUTH_DIR
  still overrides.
- No visibility: when oauth is selected but no login is seeded, the path
  silently degraded to DDG/Brave. Added gemini_oauth_ready() + a one-time debug
  hint and a startup entrypoint warning (skipped on the browser role, fail-open).
- Seeding guidance: oauth_creds.json is the essential credential (refresh token;
  GOOGLE_GENAI_USE_GCA=true forces OAuth), which is what the readiness check and
  warning verify; docs recommend copying the whole ~/.gemini for convenience.

Adds docker/gemini-oauth/ seed dir (.gitkeep) with the login files gitignored,
GEMINI_OAUTH_DIR in .env.example, and updates DEPLOY.md, stream_browser_modes.md
and llm_contexts.md. Covered by 3 new tests (10 passed total).
