Replace the ad-hoc `worker.js` with a self-contained `linearvoid-media` worker under `infrastructure/cloudflare/` that owns `media.linearvoid.tv`. It serves HLS objects from the R2 bucket, enforcing immutable Cache-Control on segments, a short TTL on live manifests, plus HLS CORS, OPTIONS preflight, Range support, and a `/health` probe. Includes wrapper config with production domain, Vitest unit tests, Miniflare R2 integration tests, automated deploy workflow, and docs updates.
