feat(stacks): add 5 .NET desktop stacks — WPF, WinUI 3, UWP, Avalonia, Uno Platform

Adds WPF, WinUI 3, UWP, Avalonia, and Uno Platform stacks (17 -> 22 total),
each with its own guidelines CSV, registered in core.py and synced to cli/assets.

- New stack CSVs in src/ and cli/assets/data/stacks/
- search.py / core.py registry updated
- smoke-stacks.sh: EXPECTED_STACK_COUNT 21 -> 22 with a smoke-test workflow
- platform template descriptions and README bumped to 22 technology stacks
