v0.1.0

First public release of captionkit — convert & re-sync subtitles, locally.

• 🔁 convert / toSRT / toVTT — SRT ⇄ WebVTT (tolerant parse, exact ms timecodes)
• ⏱️ Re-timing: shift, scale, resync (linear drift correction), fixOverlaps
• 🎬 Free local-only web app — drop a file, fix sync, download (nothing uploaded)
• 📦 Zero dependencies; ESM + CJS + TypeScript types

Web app: https://didrod205.github.io/captionkit/ · npm install captionkit
