* fix: limit catalog changes to gates entry only, revert unrelated re-serialization

Reverts the wholesale Unicode-escape and tools-array reformatting that
was unintentionally introduced across catalog.community.json. Only the
gates-specific updates remain:
- description updated to v0.3.2 wording
- version: 0.1.0 → 0.3.2
- download_url updated to gates-0.3.2.zip
- git tool required: true → false
- commands: 5 → 8, hooks: 1 → 2
- updated_at: 2026-07-13 → 2026-07-15
- changelog field added

* fix: move changelog field above license in gates entry

Move changelog URL field to sit after documentation and before license,
matching the catalog's standard field ordering. Remove the dangling
changelog at the bottom of the entry so updated_at is the final field
with no trailing comma.
