feat: enhance host resolution, filtering, and cache management

- **Strategies**: Add resolver strategy input validation and parsing in setup wizard. Support comma-separated input with known strategy mapping.
- **Client**: Extend Search and SearchAll to include kind and tag filters. Add pagination for full cache refresh handling large datasets.
- **Cache**: Introduce `RecentlyUsed` and `MarkUsed`. Persist `LastUsed` timestamps for entries.
- **TUI**: Add recent hosts view, tag/kind filters, and inline editor for user/port override.
- **Tests**: Comprehensive unit tests for new features, including strategy validation, cache behavior, and client filtering.
- **Docs**: Update README with new TUI features and cache subcommands.

-netssh cache list            # show all cached entries
-netssh cache refresh         # re-fetch all hosts from NetBox

+## Disclaimer
+
+This is a **vibe-coded** project: the entire codebase — architecture, implementation, tests, and docs — was generated by an AI assistant (Claude by Anthropic). No human has reviewed or audited the code. It works for the author's personal use case, but correctness and security are not guaranteed. Read the source before running it in sensitive environments.

 ## How it works
 
 1. `netssh` checks whether the first argument is a known subcommand (`configure`, `search`, `cache`, `completion`). If not, it enters SSH wrapper mode.
