SnapOtterandGitHub 00b651c9f8 feat(i18n): 21-language pipeline, landing/docs/API wiring, landing+API translations
Shared Claude Code translation pipeline (scripts/i18n, no API key) plus Astro/VitePress/Scalar i18n wiring. Landing and API reference translated into all 20 languages; docs i18n wiring + English source anchors. The translated docs markdown (apps/docs/<locale>/**, 3,620 files) follows in a companion PR because it exceeds GitHub's per-PR CI file limit.

## Notes {#notes}
- The response includes a `metadata` object with container format, duration, bitrate, and current tags.
- When `strip` is `true`, all tag fields are ignored and every existing tag is removed.
- Only the tags you provide are updated; unspecified tags remain unchanged.
- Output format matches the input format.
