Chore: Update TUnit to version 0.56.5 across projects and refine debouncer logic

AnnaSasDev · AnnaSasDev · commit fe76699f48e6 · 2025-08-15T11:48:04.000+02:00
Upgraded TUnit package in all projects to v0.56.5. Refined `DebouncerBase` logic to improve cancellation handling and adjusted invocation timing. Added a new debounce unit test for sustained invocations.
