feat: integrate Recall.ai SDK for automatic meeting recording

Add Recall.ai Desktop SDK integration for automatic detection and
recording of Zoom, Teams, and Google Meet meetings with real-time
status updates and management UI.

Features:
- Automatic meeting detection (Zoom/Teams/Google Meet)
- Recording lifecycle with status updates (recording → uploading → processing)
- Notetaker UI for viewing and managing recordings
- PostHog backend integration for storage and backup
- IPC handlers for renderer/main process communication

Security:
- Proper URL hostname validation (prevents substring injection)
- UUID validation for recording IDs (prevents path traversal)
- Title-based detection only as fallback with warning logs

Architecture:
- Recall SDK runs in main process with event listeners
- PostHog API client for CRUD operations on recordings
- Zustand store for UI state management
- Status updates via IPC from main to renderer

Configuration:
- Vite: externalize Recall SDK (prevent bundling)
- Forge: unpack Recall SDK from asar archive
- Initialize SDK automatically on authentication

This PR implements Phase 1B of the desktop recordings feature,
providing the foundation for future transcript streaming and
note-taking capabilities.
