feat(mcp v2.4): apps.create template pathway + apps.templates.{list,search}

Adds Coolify one-click template support — 320+ vetted apps deployable
in one MCP call (Twenty, n8n, Supabase, Ghost, etc).

- apps.create gains a 4th pathway: { template: "<slug>", ... }. Auto-
  rewrites the Coolify-assigned sslip URL to the workspace FQDN and
  applies user envs before starting.
- apps.templates.list / apps.templates.search expose the catalog so
  agents can discover slugs. Catalog is fetched from upstream GitHub
  and cached in-memory for 1h.
- lib/coolify.ts: + setServiceDomains, updateService, listService-
  Templates, searchServiceTemplates. Reuses existing createService.
- next.config.ts: externalize ssh2 + cpu-features from turbopack so
  `next build` can complete (native .node binaries can't be ESM-bundled).
