Adds an overlay for dev/docker-compose that resets the `build:` block
of every locally-built component and points it at the matching prebuilt
image from GHCR, so developers can run the stack without local builds.
Image tag defaults to "main" and is overridable via BUTTERCUP_IMAGE_TAG.

* ci: allow Docker Compose !reset/!override tags in YAML check
The static-checks YAML step uses yaml.safe_load_all, which rejects the
Compose-specific !reset/!override merge tags used by
compose.prebuilt.yaml. Register no-op constructors for those tags so
compose overlays validate without masking real YAML errors elsewhere.
