* fix(providers): use Bearer auth for Gemini CLI OAuth tokens
When credentials come from ~/.gemini/oauth_creds.json (Gemini CLI),
send them as Authorization: Bearer header instead of ?key= query
parameter. API keys from env vars or config continue using ?key=.
Fixes#194

* refactor(gemini): harden OAuth bearer auth flow and tests
* fix(gemini): granular auth source tracking and review fixes
Build on chumyin's auth model refactor with:
- Expand GeminiAuth to 4 variants (ExplicitKey/EnvGeminiKey/EnvGoogleKey/
OAuthToken) so auth_source() uses stored discriminant without re-reading
env vars at call time
- Add is_api_key()/credential() helpers on the enum
- Upgrade expired OAuth token log from debug to warn
- Add tests: provider_rejects_empty_key, auth_source_explicit_key,
auth_source_none_without_credentials
