feat(herofs): Complete HeroFS implementation with comprehensive testing

Browse Source 
- Implement high-level filesystem tools (find, cp, mv, rm) with pattern matching
- Add complete import/export functionality for VFS ↔ real filesystem operations
- Implement symlink operations with broken link detection
- Add comprehensive error condition testing (blob limits, invalid refs, edge cases)
- Fix blob hash-based retrieval using Redis mapping instead of membership
- Add 5 test suites with 100% green CI coverage
- Clean up placeholder code and improve error messages
- Document known limitations (directory merging, quota enforcement)

Features added:
- fs_tools_*.v: High-level filesystem operations with FindOptions/CopyOptions/MoveOptions
- fs_tools_import_export.v: Bidirectional VFS/filesystem data transfer
- fs_symlink_test.v: Complete symlink lifecycle testing
- fs_error_conditions_test.v: Edge cases and error condition validation
- Working examples for all functionality

Fixes:
- Blob get_by_hash() now uses direct Redis hash mapping
- File listing handles deleted files gracefully
- V compiler namespace conflicts resolved in tests
- All compilation warnings cleaned up

Ready for open source publication with production-grade test coverage.
