* feat: add enhanced error messages for file operations
Add a file_errors module that provides context-aware error messages
for file operations. When file operations fail, users now see:
- The specific operation that failed (create, read, write, rename, etc.)
- The full path involved
- Helpful hints about possible causes based on error type
- Android-specific hints for permission errors (SELinux, Work Profile,
MDM/Knox policies, app cloning features)
This helps diagnose issues like "Permission denied (os error 13)" by
indicating which operation failed and suggesting possible causes.
