Make each directory answerable by path alone: src/ is what the Remotion build
compiles, scripts/ is what you run by hand.
Removed:
- `ffmpeg.sh` — never worked; every parameter was assigned `$1`, so bake/bypass
were broken from the start. Superseded by `scripts/ffmpeg_tools.py bake|still`.
- `src/lrc2srt.ts` — the TypeScript port; `scripts/lrc2srt.py` is the script that
was actually maintained, and it now handles the multi-timestamp cases the TS
version did.
- `scripts/bom-gen.ts` — superseded by `scripts/bom_gen.py`.
- `scripts/ffmpegusage.txt` — legacy command notebook. Every recipe in it is now
reproduced by `ffmpeg_tools.py`, including the `-map 0:v:0 -map 1:a:0 -c:v copy`
mux and the FLAC `-compression_level 12` case, so it has no unique content left.
Also drops the `bom-gen` alias from the dispatcher (dash-case was TypeScript
naming) and documents the boundary in README.md and REMOTION-QUICKSTART.md.
`npm run lint` (eslint src && tsc) passes with src/ reduced to Remotion input.
