Improved Path Security Validation

What: Enhanced validation for file system commands with clearer security messages Why: Provides better security boundaries and more helpful error messages when paths are restricted How to use: Path validation is automatic for commands like cd, ls, and find. When blocked, you'll see specific messages like:

cd in '/restricted/path' was blocked. For security, Claude Code may only 
change directories to the allowed working directories for this session: [list]

Details:

• Better handling of glob patterns (*, ?, [, ], {, })
• Proper tilde expansion (~ and ~/ paths)
• Improved handling of relative paths with ..
• More specific error messages for each command type
