Recreate only the edge runtime on deploy

The deploy gate ran docker compose up --force-recreate functions, which also starts what functions depends on: kong, and through kong studio. studio has been down since the stack restarted on 2026-10-12, so compose stopped with "dependency failed to start: container supabase-studio exited (128)" after removing the old runtime, and left the new one in Created: every edge function answered 503 until it was started by hand. --no-deps recreates the runtime alone; checked with compose --dry-run on the host (with deps: the studio error; with --no-deps: recreated and started). The host's gate is updated to this file, so the deploy's hash check matches.
