Jiří Polášek 49cc504d94 CmdPal: Improve fuzzy matcher Unicode and emoji robustness (#45275)
## Summary of the Pull Request

Add comprehensive unit tests for emoji, ZWJ sequences, skin tone
modifiers, and UTF-16 edge cases (unpaired surrogates, combining marks,
random garbage). Update matcher logic to skip normalization of lone
surrogates, preventing errors with malformed Unicode. Expand comparison
test data to cover emoji scenarios. Adds regression guards for diacritic
handling and surrogate processing.

Fixes #45246 introduced in #44809.

PowerToys Source Code

Code organization

The PowerToys are split into DLLs for each PowerToy module (modules folder), and an executable (runner folder) that loads and manages those DLLs.

The settings window is a separate executable, contained in settings-ui folder. It utilizes a WebView to display an HTML-based settings window.

The common contains code for a static library with helper functions, used by both the runner and the PowerToys modules.
