## Summary
The `registry.westgate.pw/deployment/crucible` image has no consumer: `prod.yml` no longer reserves a slot for it (contract settled in sow-platform PR #64) and no runtime or recovery path pulls it. Binaries, wrappers, and the Nix input remain the supported ways to run Crucible.
## What changed
- Deleted `.gitea/workflows/build-image.yml`, `publish-image.yml`, `test-image.yml`
- Deleted `docker/Dockerfile` and the `make image` target
- Updated README, AGENTS.md, and `docs/consumer-contract.md` to state the image is retired
Existing `deployment/crucible` images in the registry can be deleted at leisure; nothing references them.
