- Benchmark tab: scrollable engine checklist above Run with live
reachability dots (green/red), name+model+URL filter, All/None buttons;
_run_bench respects selection and shows clear message when nothing ticked
- About tab: changelog now rendered via _md_panel (markdown headers, bold,
lists) instead of plain monospace _text_panel
- Manual tab: graceful fallback with clickable GitHub link when MANUAL.md
is not installed; build-deb.sh now copies MANUAL.md from repo root so
/opt/blitztext/MANUAL.md exists in future installs
- STT quickstart templates expanded: Speaches docker, whisper.cpp server,
NVIDIA NIM/Parakeet, five built-in local model sizes (tiny→large-v3)
