Update IMPLEMENTATION.md and fix Phase 2 issues

Add dependency validation, batching, and progress feedback to OCR pipeline
Improve error handling and cross-platform compatibility
Refactor GLM-OCR client to use file-based requests with auth
Remove base64 dependency and use native Node.js file operations
Optimize notebook detection and page file discovery
Cache sync tracker data to reduce disk I/O
Update default settings to use localhost endpoints
Fix manifest.json and increase build size to 17 KB
