`crossplane dependency update-cache` does not add XRD types into `schemas/` (inconsistent with `crossplane project build`)

crossplane project init、apis/ 配下の XRD、および crossplane dependency update-cache を使って問題を再現します。schemas/.lock.json と生成された schemas を調査します。fs://apis エントリを追加する crossplane project build と結果を比較します。update-cache が XRD schemas を含め、完全な build を必要とせずに lock ファイルを更新すれば完了です。

What happened?

After running crossplane dependency update-cache, schemas/.lock.json does not include entries for XRD schemas defined under apis/. Only running crossplane project build updates the lock file and adds a fs://apis key with the generated schemas.

This makes the two commands inconsistent: one partially updates the cache/lock file, the other fully updates it. In practice this breaks the local dev loop — since update-cache doesn't pick up XRD changes, a full project build is required after every schema edit just to regenerate the schemas needed to keep developing a function.

I expected update-cache to update the lock file and the schema types consistently, including XRD schema entries, without requiring a full build.

How can we reproduce it?

1. crossplane project init my-project
2. Add dependencies to crossplane-project.yaml
3. Add an XRD definition to apis/
4. crossplane dependency update-cache
5. Inspect schemas/ — the lock file does not contain the fs://apis key, and no schemas were generated for it
6. crossplane project build
7. Inspect schemas/ again — the lock file now contains fs://apis, and the schemas have been generated

What environment did it happen in?

• Crossplane CLI version: 2.4.0
• Platform: linux/amd64
