feat: Add verbose mode with worker lifecycle monitoring and improved error handling

Adds --verbose flag to init and index commands that shows timestamped progress output instead of animated progress bars. Implements worker timeout protection (10s per file) and periodic worker recycling (every 500 files) to prevent WASM memory crashes from hanging the entire indexing process. Includes detailed logging of worker lifecycle events and memory usage for debugging large repository indexing issues.
