fix(runner): correct PUBLIC_URL + mount runner-map volume
Two overlapping bugs were killing OAuth discovery for every external
MCP client (Claude Desktop, Cursor, etc.):

1. worker.ts injected PUBLIC_URL=http://<RUNNER_HOST>:<port> into the
   runner container even when MCP_DOMAIN was set. Result: the runner's
   /.well-known/oauth-protected-resource advertised an unreachable URL
   and the WWW-Authenticate header pointed at a non-HTTPS loopback
   address. Claude Desktop refused to follow the discovery chain.
   Now derives PUBLIC_URL from the same computePublicUrl() helper that
   builds the user-visible URL stored in mcp_servers.public_url, so the
   container's self-reported resource matches its actual route.

2. docker-compose.prod.yml never mounted /opt/buildmymcpserver/runner-map
   into the api / generator containers. The .conf snippet written by
   the generator landed in an ephemeral container path; the host
   inotify watcher saw an empty directory and produced an empty
   runner-map.combined. Result: nginx 404'd every /<slug>/* request,
   the runner was unreachable from the public domain, and OAuth
   discovery couldn't even begin. Mount added to both services.

Existing weather server has the wrong PUBLIC_URL baked in and must be
recreated after deploy. No customers yet.

export computePublicUrl from deploy.ts so worker.ts can call it.

# Production stack for buildmymcpserver.com — Linux host only.
#
# Run with:
# docker compose --env-file .env.production -f docker-compose.prod.yml up -d --build
#
# Topology — matches the house pattern on the shared Hetzner box:
# - Bridge networking + per-app network, like every other app on the box.
# - api / web / postgres / redis publish to 127.0.0.1 only. The host nginx
# reverse-proxies the public domains to these loopback ports. Nothing here
# binds 0.0.0.0:80/443 — the box's existing nginx owns those.
# - generator uses host networking: it has no listening port of its own (no
# collision risk) and it must allocate + probe host ports for the MCP
# containers it spawns, which is only correct in the host namespace.
# - api + generator mount the Docker socket: the API removes generated
# containers, the generator builds + runs them as host siblings.
#
# Ports are picked to not collide with the other apps already on this box.
