Implemented `GeminiLanguageModel`, providing an adapter for Google's Gemini models conforming to Apple's `FoundationModels.LanguageModel` protocol. This PR includes text to text generation capabilities; other modalities and Gemini features will be handled in follow-up PRs. **Note:** The `GeminiLanguageModel` implementation is guarded by the environment variable `GEMINI_LANGUAGE_MODEL`. By default none of the `GeminiLanguageModel` implementation is included. Key additions: - `GeminiLanguageModel`: Implements `LanguageModel` protocol with reasoning capabilities, configuring execution via `ModelResource` and `EndpointConfiguration`. - `GeminiLanguageModelExecutor`: Converts prompt instructions and history into Gemini streaming requests, yielding responses as `LanguageModelSession.ResponseStream`. - `GeminiTranscriptTranslator`: Translates Apple `Transcript` entries and segments into Gemini `Content` structures while preserving thought signatures and validating supported transcript features. - `GeminiLanguageModel.Error` and `GeminiErrorMapper`: Translates Gemini API, HTTP, and network errors into standard `LanguageModelError` cases (`rateLimited`, `timeout`, `guardrailViolation`, `refusal`, and `unsupportedLanguageOrLocale`) or `GeminiLanguageModel.Error` cases (`serviceUnavailable`, `networkFailure`, `modelNotFound`, `apiError`). The `APIError` payload is designed for seamless forward compatibility with both GenerateContent and the upcoming Interactions API. - Testing infrastructure: Adds `ConditionTrait.requireFoundationModels` to conditionally run Foundation Models tests only on supported platforms (macOS 27+, iOS 27+, watchOS 27+, visionOS 27+), along with shared test constants, mock fixtures, and comprehensive unit and integration test suites.
