Add CC0-1.0, CC-BY-3.0, and the CC-BY-NC* family to the license policy

Mirrors the statistical-genomics-foundry instance (cross-repo shared table,
foundry-pattern#4). Its corpus surfaced source notes under these ids resolving
to the default/defect row.

- CC0-1.0, CC-BY-3.0 → verbatim-ok (CC0 vendors the legalcode on verbatim carry,
  uniform with license_file_tracks_verbatim).
- CC-BY-NC-4.0/3.0/2.5/2.0-UK, CC-BY-NC-ND-4.0 → own-words-only: the license
  permits NC verbatim reproduction, but the NC condition would propagate into
  casts. Same reasoning the existing CC-BY-NC-SA-2.0 row applies.
- meta_schema.yml license enum extended in lockstep (tests/license-policy.test.ts).
