Add CLAUDE.md, collection scaffold, and MemPalace wing

Establish this repo as a collection of independent script folders for the
self-hosted environment (odin, an Unraid host).

- CLAUDE.md: repo conventions, the odin stack, and MemPalace usage. The
  infrastructure facts are carried over from the FamilySync project, where
  they are documented and verified; the mapping of the name "odin" to that
  host is assumed and flagged for confirmation, along with the SSH/deploy
  gaps marked "?".
- Core rule: each collection is a self-contained top-level folder owning its
  own docs, config, and dependencies. No shared/ or utils/ at the root —
  duplication is preferred over coupling so a collection stays independently
  deletable.
- _template/: scaffold making that rule concrete. The bash entrypoint ships
  strict mode, --dry-run, and a required-env guard (all four paths tested).
- mempalace.yaml: wing "odin-scripts", set explicitly because basename
  auto-detection would produce the colliding wing "scripts". Tracked rather
  than gitignored so a fresh clone keeps the config; entities.json stays
  ignored.
