Add section 10.1 covering tag-triggered CI build, version from git tag flowing into both ldflags and the image tag (enforcing the 7.5.A restore invariant), and publishing to ghcr.io. Document Quay.io as an alternative registry. Update 11.7 (GitHub is no longer a dumb mirror) and add the workflow as deliverable 11.10. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
