Remove CI/CD, unify Docker image for Docker Hub and HA add-on

- Remove GitHub Actions workflows (ci.yml, docker.yml, release.yml)
- Remove GoReleaser configuration
- Remove RELEASE.md (replaced by /release_strix skill)
- Add HA options.json support in config.go (reads /data/options.json)
- Add Version field to Config, pass real version to health endpoint
- Change Version from const to var, inject via ldflags at build time
- Add ARG VERSION to Dockerfile for build-time version injection
- Reset webui/package.json version to 0.0.0 (not used functionally)
- Clear probe fields on back navigation in frontend
- Add /release_strix and /release_strix_dev skills
