Snapshot of the working tree before cleanup. Captures: - Keysat licensing: server/license.js, /api/license/* endpoints in server/index.js, activation modal in public/index.html, embedded Ed25519 issuer key (assets/issuer.pub). - StartOS 0.4 expansion: setApiKey action, version files v0.1.1 through v0.1.15, file-models/config.json.ts, manifest updates. - Self-hosted registry server (startos-registry/). - Build/deploy scripts (bin/bump-version.sh, bin/deploy.sh, vendored yt-dlp binary), .gitignore, .deploy.env.example. - Recent design docs (KEYSAT_INTEGRATION.md, UPGRADE-DESIGN.md) — retained here so they remain recoverable when removed in the follow-up cleanup commit.

negotiator = new Negotiator(request)
// Let's say Accept header is 'text/html, application/*;q=0.2, image/jpeg;q=0.8'
negotiator.mediaTypes()
// -> ['text/html', 'image/jpeg', 'application/*']
negotiator.mediaTypes(availableMediaTypes)
// -> ['text/html', 'application/json']
negotiator.mediaType(availableMediaTypes)
// -> 'text/html'

Accept-Language Negotiation
negotiator = new Negotiator(request)
availableLanguages = ['en', 'es', 'fr']
// Let's say Accept-Language header is 'en;q=0.8, es, pt'
negotiator.languages()
// -> ['es', 'pt', 'en']
negotiator.languages(availableLanguages)
// -> ['es', 'en']

negotiator = new Negotiator(request)
// Let's say Accept-Charset header is 'utf-8, iso-8859-1;q=0.8, utf-7;q=0.2'
negotiator.charsets()
// -> ['utf-8', 'iso-8859-1', 'utf-7']
