Introduces a provider abstraction so the AI coach can run on Google Gemini in addition to OpenAI, selectable in Settings. The user's Gemini key is stored only in the iOS Keychain. - GeminiClient: adapts the app's ResponsesClient protocol to Gemini's generateContent API, translating request/response shapes and tool calls. Maintains conversation state across turns since the OpenAI Responses API is stateful but Gemini is not. - GeminiKeychainStore: separate Keychain entry so OpenAI/Gemini keys coexist. - Settings: provider picker, per-provider model list, and a Gemini key field mirroring the OpenAI one. - Coach view model, summary, and notification services resolve the active client from the selected provider. Schema handling for Gemini: rewrites JSON Schema union types (["string","null"]) to nullable, strips unsupported keywords, and omits the response schema on tool turns (Gemini rejects tools + responseSchema together), relying on the orchestrator's tool-less repair turn for the final structured output.

Adds Google Gemini as an opt-in alternative to the existing OpenAI coach, behind a provider-agnostic adapter so no other component needs to know which provider is active.
