[github-actions]

Update API specifications by running fern api update.

Note

Medium Risk
Medium risk because it changes the public API contract (new required fields, renamed fields, and new query params) which can be breaking for generated SDKs and existing clients relying on the previous schema.

Overview
Updates the OpenAPI spec generated by Fern to introduce first-class ADR support and several import/listing contract changes.

Adds new ADR schemas plus corresponding TaskType entries and socket client/server events for listing and subscribing to ADR updates.

Enhances landscape import/export and catalog listing contracts: adds prune support (query param + response field) and import metadata counts, allows YAML import bodies, introduces cursor/limit pagination for catalog/technologies (with nextCursor + x-fern-pagination), loosens/tightens various import/filter shapes (e.g., ImportIcon.technologyId rename, ModelObjectImport.parentId no longer required, optional namespace, and filter arrays capped at 30).
