Subject: [PATCH] feat: dynamic manifest in Cloudflare Worker with cookie-based
 org identification

Adds parseOrgIdFromCookie and buildManifest exports to the worker, intercepting /manifest.webmanifest to serve org-specific PWA icon URLs based on the x-org-id cookie. Removes legacy @ts-nocheck and biome-ignore-file comments.
