* docs(skills): reverse asks to top up once for the run's total

* docs(skills): reverse builds the project with init --video

* test(skills): pin reverse's init --video and top-up-once wording

 1. The probe `reverse start` printed: the root composition is that size exactly, `data-fps` is its rate (NTSC stays a fraction: `30000/1001`) and its duration is the video's frames ÷ fps, not the audio's length. `init`'s default canvas is wrong for most videos.
 2. `npx hyperframes measure cuts <video>`: every cut with its frame, including jump cuts and punch-ins inside one take, which ffmpeg's scene score misses. Every shot starts at its listed time. Write times as frame ÷ fps rounded down (frame 83 at 30 fps is `2.766666`): `2.767` lands a frame late.

 4. Read consecutive frames wherever something changes: each cut, entrance, exit and transition, a few frames either side (`npx hyperframes measure frames --range a,b --roi x,y,w,h`). Sheets a second or a quarter apart miss 1–3-frame timing, which way things enter and leave, blurs and dissolves at cuts, and one-frame flashes.
