Closes #1–#6 (Forgejo jared/cc-os).
- Reconcile vault-conventions.md to a single authoritative frontmatter schema (#1)
- Add memory-template plugin skill: template-design + new-type-creation (#2)
- Add howto/convention/reference note templates, each dogfooded (#3–#5)
- Patch 4 proof-of-concept notes to the settled schema (#6)
Note: vault note files (templates, patched notes, vault-conventions.md) live in the separate ~/Documents/SecondBrain repo and are committed by its own SessionEnd hook; this commit covers only the cc-os-tracked files (skill + docs).
