[github-actions]

Summary

Adds a new Body Hash entry to the reference glossary and updates the existing Frontmatter Hash entry to cross-reference it.

What changed

File	Change
docs/src/content/docs/reference/glossary.md	Added Body Hash glossary entry; updated Frontmatter Hash entry with cross-reference

Details

New: Body Hash glossary entry

• Defines the Body Hash as the SHA-256 hash of a workflow's markdown body (content below the frontmatter).
• Documents its relationship to on.stale-check: "full", explaining that this mode uses the body hash (in addition to the frontmatter hash) to detect staleness.

Updated: Frontmatter Hash glossary entry

• Added a cross-reference to the new Body Hash entry for reader discoverability.

Impact

• Docs only — no code, schema, or behaviour changes.
• Breaking: No.
• Affected audiences: Users configuring on.stale-check: "full" who need to understand what triggers a stale re-run.
