ScreenTinker c2240288a7 Serve the service worker from the root, so its scope needs no header to survive
Found deploying 1.9.29 to production. A worker's scope defaults to its own
directory, so /player/sw.js could only control /player/ and below; the fix was to
request a wider scope and permit it with Service-Worker-Allowed. That works right
up until something between the origin and the browser does not pass the header
on. Cloudflare served a CACHED response for that path across the deploy —
headers and all — and the registration failed outright.

A rejected registration is worse than a narrow one: the player runs with no
worker at all, on every URL, and nothing about it is visible from the server. The
origin was sending the header correctly the whole time; a cache-busted request
proved it. It self-heals when the edge entry expires, which is precisely the kind
of fix nobody should have to know about.

Served from /, the default scope is already the whole origin and no header has to
survive the trip — through Cloudflare, through whatever a self-hoster puts in
front of it, or through a corporate proxy we will never see. /player/sw.js keeps
serving for players still asking for it, and the header is still sent where it
does survive.

Verified in a real browser: all three of /player, /player/ and /player/index.html
are controlled from root scope.
