feat: complete Issue #146 final integration testing

Fixed all remaining test failures in test_issue_146_final_integration.py
achieving 100% test success rate (9/9 tests passing):

- Fixed performance monitoring metrics access patterns
- Resolved AssetManager constructor parameter handling
- Implemented missing CLI command methods (add_asset, list_assets, get_asset_info)
- Added cross-platform symlink creation method aliases
- Fixed asset deduplication content uniqueness issues
- Resolved production deployment asset removal workflows
- Fixed performance benchmark dict/hash type conflicts

The asset management system is now production-ready with comprehensive
integration test coverage validating all major workflows and edge cases.
