Skill no longer aborts on bare `Get-Command yt-frames` miss — binaries
installed in project-local venv or winget cache (Gyan.FFmpeg_*) are
valid install sites, just not on PATH for fresh shells.
New Step 0 in both flows: probe PATH first, then known install
locations (venv Scripts/bin, winget Gyan.FFmpeg_*/ffmpeg-*-full_build/bin);
abort only if both empty. PATH-prepend pattern documented (full-path
to yt-frames.exe is insufficient — child yt-dlp/ffmpeg need prepend
too).
Failure modes table updated: removed 'restart CC session' advice —
agent can't restart itself, and resolve-fallback makes it unnecessary.
MINOR bump per project-discipline (behaviour change in resolve logic).
