address review: fix test, changelog and models.json newline

- Update packages/catalog/test/meta-provider.test.ts to expect
  three META_MUSE_STATIC_MODELS entries (1.1, 1.2, contributor)
  with input ["text","image"] — fixes blocking failure.

- Add ## [Unreleased] entry in packages/catalog/CHANGELOG.md per
  AGENTS.md.

- Remove trailing newline from models.json to match
  generate-models.ts (Bun.write without \n).

 ## [Unreleased]

+- Marked `meta/muse-spark-1.2` and `muse-spark-1.2-contributor` as image-capable (`input: ["text", "image"]`) with the same Responses reasoning, thinking, and cost metadata as `muse-spark-1.1` (contributor uses its discounted 0.1/0.2 pricing), so `omp models` no longer lists them as text-only.
