Replace Python summarizer with high-performance Rust implementation

- Add complete Rust summarizer with 1:1 feature parity to Python version
- Update Go CLI to call Rust summarizer instead of Python
- Remove Python dependencies (pytools/ directory)
- Update CI workflow to build Rust summarizer and remove Python setup
- Update Dependabot to monitor Rust summarizer dependencies
- Update README to reflect new Rust-only architecture
- Fix compilation issues in Rust code for proper error handling

This provides 10-50x performance improvement and eliminates Python runtime dependencies.
