docs: version distributable artifacts

[DerekCorniello]

Summary

• adopt artifact-based SemVer instead of versioning every repository
• define immutable commit and image-digest identity for rolling repos and deployments
• add the release-manifest policy and supersede the old independent-versioning decision

Verification

• python3 scripts/ci/check-docs.py
• python3 -m unittest discover -s scripts/tests -p 'test_*.py'\n\nThis is documentation and governance only. No release, tag, deployment, or product code change.

Greptile Summary

The PR replaces repository-wide independent versioning with artifact-based versioning and defines immutable identities for rolling deployments.

• Adds ADR 0007 and supersedes the prior independent-versioning policy.
• Defines the GitHub Release body as the compiler release manifest.
• Splits manifest recording into build-time and post-deployment phases.
• Aligns the release guide, glossary, ADR index, README, and agent index with the new policy.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.
