Updates OCGV and SHOT to Terminal.Gui v2

[tig]

PR Summary

Phase 1: Port existing ListView based implementation to v2.

Remaining Work

• [x] Figure out why it crashes on start
• [x] Improve project setup to make debugging easier. I got VS2026 working!
• [ ] Manual testing of all features (Out-ConsoleGridView, Show-ObjectTree)
• [ ] Verify filtering, selection modes, MinUI functionality
• [ ] Confirm command-line backwards compatibility
• [ ] Unit test framework + initial test coverage (future enhancement)

Phase 2: Refactor to use TableView instead of ListView.

This will both simplify the implementation, but improve usability, perf, and scalability.

PR Context

• Fixes #249
