Major improvements to Gemini provider:
**Shared Conversation History**
- Add ConversationMessage interface for provider-agnostic history
- Both Claude and Gemini agents read/write shared conversationHistory
- Context persists across provider switches via claudeSessionId linkage
**Multi-Turn Gemini API**
- Replace stateless single-query with full conversation context
- queryGeminiMultiTurn() sends entire history for coherent responses
- Maps 'assistant' role to 'model' for Gemini API compatibility
**Automatic Fallback to Claude**
- Detect rate limits (429), server errors (5xx), network failures
- Fall back to Claude SDK when Gemini API fails
- Reset 'processing' messages to 'pending' before fallback
**Mid-Session Provider Switching**
- Track currentProvider on ActiveSession
- Provider changes take effect after current generator finishes
- Avoids race conditions from aborting active generators
Files changed:
- worker-types.ts: Add ConversationMessage, currentProvider tracking
- GeminiAgent.ts: Multi-turn queries, fallback logic
- SDKAgent.ts: Capture messages to shared history
- SessionManager.ts: Initialize new session fields
- SessionRoutes.ts: Provider selection and switching logic
- worker-service.ts: Wire up fallback agent dependency
