WinSnipper: vanhemmat versiot ja versiohistoria

WinSnipper 0.9.1 reduces repeated screenshot-opening work and keeps native capture waits off the UI thread.
- Reuse the screenshot selection window between snips, clear idle pixels, and reset selection mode, cached targets and screen bounds before each capture.
- Capture screenshots and run startup capture warmup on a dedicated bounded worker. Reserve selection while pixels are pending and recover cleanly after capture failures.
- Give hotkey handoff its own bounded worker, separate from the native keyboard callback and the general thread pool.
- Add per-opening render, keyboard handoff, capture queue/work/UI-resume, effective priority and GC diagnostics without retaining old traces or the idle worker's last bitmap.

- WinSnipper-OCR.exe: adds Windows OCR and Windows.Graphics.Capture recording, 27,535,212 bytes.
Windows 10/11 and the .NET 8 Desktop Runtime are required. Existing settings and capture folders are retained. Optional ADE attachments require a compatible capture-protocol-v1 receiver; see requirements.
Both exact release executables passed sequential screenshot/hook/OCR-where-supported/recording/trim smoke tests. The 11 capture/shortcut test groups and 24 failure-path checks passed. Real heavy-workload visible latency, sleep/resume and extended recording are not established by those checks; this release makes no universal speed guarantee. Performance evidence.
