feat: switch workspace provisioning from Coolify to Cloud Run

- lib/cloud-run-workspace.ts: provisions per-project Theia workspaces as
  Cloud Run services (theia-{slug}), scales to zero when idle, starts in
  ~5-15s from cached image
- create/route.ts: imports cloud-run-workspace instead of coolify-workspace
- Image: northamerica-northeast1-docker.pkg.dev/master-ai-484822/vibn-ide/theia:latest
- Includes prewarmWorkspace() for near-zero perceived load time on login
