Docs: commit basic-memory frontmatter backfill + resolved MCP lock hash

The 13 vault notes were left dirty by basic-memory back-filling
title/type/permalink frontmatter into files written with Write/Edit
(it also strips the trailing newline — restored here so future diffs
stay clean). Content is unchanged; verified frontmatter-only.

packages-lock.json is the com.coplaydev.unity-mcp #main branch ref
silently re-resolving. Pinning that dependency lands with the package
cleanup batch.
