Switches the StatefulSet from a fleet node to celld dev: local object store, one Wrangler project, no bucket. Installs esbuild in an init container. An empty hostPath uses the placeholder worker with --no-watch.

In `@templates/statefulset.yaml`:
- Line 13: Update the development-volume condition near $placeholder and $bucket
so an empty dev.hostPath renders the ConfigMap placeholder volume required by
the esbuild init container, while keeping $placeholder false so celld-deploy
remains disabled in development. Use a separate condition for the ConfigMap
volume rather than reusing the celld-deploy placeholder flag.

Render a development placeholder volume for empty dev.hostPath.
When dev.enabled=true and dev.hostPath="", line 13 clears $placeholder, but the esbuild init container still mounts placeholder and reads /placeholder. The placeholder volume is rendered only when $placeholder is true, so Kubernetes rejects the Pod template because the mount has no matching volume.
Add a separate development-placeholder condition for the ConfigMap volume. Keep $placeholder false so celld-deploy remains disabled for development.
