Comet 0.4.2

Patch release for expanded OpenAPI schema model generation.

Added

• OpenAPI component schemas can now alias local component $refs.
• Component object properties with inline object schemas now generate nested Swift structs.
• Arrays whose items are inline object schemas now generate nested Item structs.

Fixed

• Local schema $ref lookup now preserves raw OpenAPI component keys before generating Swift type names, so references such as #/components/schemas/pet-alias resolve correctly.

Verification

• git diff --check
• swift test --disable-xctest
• .github/scripts/check-api-breaking-changes.sh v0.4.1
