refactor(deps): add ai to devDependencies catalog for testing

Add ai package to catalog:dev (^6.0.7) for development and testing,
separate from the peer dependency range (>=5.0.108 <7.0.0).

Also add @ai-sdk/* and ai to minimumReleaseAgeExclude since AI SDK
releases frequently and we want to stay up-to-date.
