Adds `gemini` as a first-class buzz-agent provider using Google's OpenAI-compatible surface, so it reuses the existing Chat Completions request/response path rather than introducing a second serializer/parser. Provider contract (RESEARCH/GEMINI_PROVIDER_API_CONTRACT.md): - Provider id `gemini`; env vars `GEMINI_API_KEY`, `GEMINI_MODEL`, optional `GEMINI_BASE_URL` (default https://generativelanguage.googleapis.com/v1beta/openai). - Static `Authorization: Bearer $GEMINI_API_KEY`; `/models` discovery reuses the OpenAI-compatible path with the same bearer and key-redacted errors. - API shape pinned to Chat Completions — never Responses or native generateContent (there is no /responses endpoint on the Google host). Changes: - buzz-agent config.rs: `Provider::Gemini` variant, `resolve_provider` + `from_env` arms reading GEMINI_* with the Google default base URL, API pinned to Chat. Extracted `GEMINI_DEFAULT_BASE_URL` constant. - buzz-agent llm.rs: route Gemini through the OpenAI Chat arms and the static bearer token source. Extracted `should_use_responses` so a Chat-pinned provider can never be routed to /responses regardless of host/auto-upgrade. - desktop agent_models.rs: provider-aware base-URL/key resolution so `/models` discovery reads GEMINI_BASE_URL/GEMINI_API_KEY; Gemini ids pass through the OpenAI text-model filter unchanged. - desktop readiness.rs: require GEMINI_API_KEY and accept GEMINI_MODEL fallback. - frontend personaDialogPickers.tsx: provider option, credential mapping, and explicit-model requirement. Tests: new coverage in config.rs, llm.rs, agent_models_tests.rs, readiness.rs, and editAgentProviderDiscovery.test.mjs. Full local gates green: buzz-agent + desktop Tauri unit tests, desktop TS tests, typecheck, biome, clippy (workspace + Tauri), rustfmt.
