Major type system refactoring and error fixes across the codebase:

**Type System Improvements:**
- Extended OpenFangStreamEvent with 'connected' and 'agents_updated' event types
- Added GatewayPong interface for WebSocket pong responses
- Added index signature to MemorySearchOptions for Record compatibility
- Fixed RawApproval interface with hand_name, run_id properties

**Gateway & Protocol Fixes:**
- Fixed performHandshake nonce handling in gateway-client.ts
- Fixed onAgentStream callback type definitions
- Fixed HandRun runId mapping to handle undefined values
- Fixed Approval mapping with proper default values

**Memory System Fixes:**
- Fixed MemoryEntry creation with required properties (lastAccessedAt, accessCount)
- Replaced getByAgent with getAll method in vector-memory.ts
- Fixed MemorySearchOptions type compatibility

**Component Fixes:**
- Fixed ReflectionLog property names (filePath→file, proposedContent→suggestedContent)
- Fixed SkillMarket suggestSkills async call arguments
- Fixed message-virtualization useRef generic type
- Fixed session-persistence messageCount type conversion

**Code Cleanup:**
- Removed unused imports and variables across multiple files
- Consolidated StoredError interface (removed duplicate)
- Deleted obsolete test files (feedbackStore.test.ts, memory-index.test.ts)

**New Features:**
- Added browser automation module (Tauri backend)
