/**
* tool-youtube-transcript extension — registers the `youtube_transcript` tool
* backed by a self-hosted transcriber service on activation.
*
* The base URL comes from `YOUTUBE_TRANSCRIBER_URL` (env) with a Tailscale
* default. Effects (`globalThis.fetch`) come from the ambient edge here, in
* the shell — never in the pure core. Logging is left to the host via
* `host.logger`/`ctx.log` (no `console.*`, no hand-rolled logger).
