merge: resolve conflicts and merge include_public_api_only into main

- Resolve merge conflict in pylibfinder_tui.py by using Score field instead of Similarity
- Keep better error handling and threshold validation from include_public_api_only branch
- Apply defensive programming with .get() for missing Score keys
- Merge features: type detection, private API filtering, and TUI
- Fixes #3 (include public APIs only) and #4 (type information)
