* Support mentioning filenames with spaces
Allows spaces to be escaped in mentions with \. Does not attempt more
comprehensive escape handling. (IMO a more structured representation or
moving to something like @[something complex] is probably a better long
term approach, but the scope of that seems problematic.

Enhance the mention regex to properly support:
- Windows paths with drive letters (C:\folder\file.txt)
- Windows network shares (\\server\share\file.txt)
- Windows relative paths (folder\file.txt)
- Paths with escaped spaces in both Unix and Windows formats
- Maintain compatibility with existing URL, git hash, and keyword patterns
- Add comprehensive test suite with 200+ test cases validating all path formats
and edge cases to ensure reliable pattern matching across platforms.
