feat: Phase 10 - UI Notifications (request-only)

Implement visual feedback for MCP tool calls with configurable notifications.

Features:
- Real-time notifications when tools are called (request only, no completion)
- Tool-specific emoji icons for visual clarity
- Rate limiting (max 10 notifications/second)
- Notification history tracking (last 100 entries)
- Configurable settings: enable/disable, show parameters, duration, console logging
- History modal with filtering and export to clipboard

Implementation:
- Created NotificationManager with queue-based rate limiting
- Created NotificationHistoryModal for viewing past tool calls
- Integrated into tool call interceptor in ToolRegistry
- Added notification settings UI section
- Added 'View MCP Notification History' command

Benefits:
- Visual feedback for debugging and monitoring
- Transparency into AI agent actions
- Simple on/off toggle, no complex verbosity settings
- Zero performance impact when disabled
- History tracks success/failure/duration for all calls

All 10 phases of the roadmap are now complete\!
