PR #1447 added `capture video` as a citty subCommand. citty's runCommand (node_modules/.bun/citty@0.2.2/.../dist/index.mjs:209-227) treats any non-flag positional as a subcommand-name attempt and throws E_UNKNOWN_COMMAND when it doesn't match — there's no fallback to the parent's positional args, so `hyperframes capture https://vercel.com` died with "Unknown command https://vercel.com". Per James's suggestion, surface video-download as `capture --video <project>` (a mode flag) instead of a subcommand. Citty has no issue with a positional URL coexisting with flags. `video.ts` now exports `runVideoMode()` instead of a `defineCommand` default export. - `hyperframes capture <url>` works again - `hyperframes capture --video <project> --index N` downloads video - `hyperframes capture --video <project> --list` lists manifest - `hyperframes capture --video <project> --video-url <url>` downloads by URL
