Merge Java file support from PR #9

Add comprehensive Java file analysis support to get_file_summary function:
- Package declarations
- Import statements
- Class definitions
- Interface declarations
- Enum definitions
- Method signatures

Resolves merge conflicts while preserving all master branch features
including regex search support and improved glob pattern handling.
