v0.2.0 — subtitle CLI

⌨️ New zero-dependency CLI

```bash
npx captionkit convert subs.srt --to vtt > subs.vtt
npx captionkit shift subs.srt --ms 2000 # delay everything by 2s
npx captionkit scale subs.srt --factor 1.0427 # fix 23.976→25fps drift
npx captionkit fix subs.srt # remove overlaps
cat subs.srt | npx captionkit info # cue count + duration
```
Commands: convert, shift, scale, fix, info. `-o/--out` to write a file. Exact millisecond timecode math.

Still zero dependencies.
