Rename project: youtube-summarizer → recap

The product was always more than YouTube — it handles podcast feeds
too, and the upcoming multi-provider work makes it less Gemini-
specific. New name: Recap.

This is a coordinated identity change across:

  • StartOS package id: youtube-summarizer → recap
    (manifest.id; the .s9pk filename, Docker image namespace, and
    install path under StartOS all derive from this automatically)
  • Display name: "YouTube Summarizer" → "Recap"
    (manifest title, activation screen heading, page <title>, console
    log on boot, i18n strings, ABOUT.md, Dockerfile header,
    docker_entrypoint banner)
  • Keysat product slug: youtube-summarizer → recap
    (server/license.js PRODUCT_SLUG; frontend fallback strings)
  • Daemon subscription id: youtube-summarizer-sub → recap-sub
  • Env var prefix: YT_SUMMARIZER_* → RECAP_*
    (LICENSE_KEY, LICENSE_KEY_PATH, MAX_OFFLINE_DAYS,
    VALIDATE_INTERVAL_MS)
  • localStorage keys: yt-summarizer-* → recap-*
    (gemini-key, activation-skipped, clips)
  • Library export filename: youtube-summarizer-library.json →
    recap-library.json
  • npm package names: youtube-summarizer-{startos,server} → recap-*
  • Deploy paths: youtube-summarizer_x86_64.s9pk → recap_x86_64.s9pk
    (default values in bin/deploy.sh; .deploy.env on dev machine
    needs the same update before next push)
  • Self-hosted registry directory: startos-registry/packages/
    youtube-summarizer → .../recap (with package.json + INSTRUCTIONS
    rewritten)

What does NOT change:
  • Filesystem repo path (still /Users/.../youtube-summarizer/)
  • Git history / commit messages
  • Existing version files in startos/versions/ (kept as-is — the
    version chain belongs to the package's own history regardless of
    its display name)

User-side follow-ups required:
  1. Create "recap" product in Keysat admin, set up Core/Pro tier
     policies (same entitlements as before), mint a fresh test
     license. Old "youtube-summarizer" licenses won't activate
     against the new slug.
  2. Update .deploy.env (gitignored) so FILEBROWSER_PATH and
     REGISTRY_PUBLIC_URL point at recap_x86_64.s9pk.

StartOS will treat this as a brand-new app on install — existing
youtube-summarizer installs will not auto-migrate (acknowledged
intentional given no real users yet).
