[BUG] `dependencies` hook is not triggered when dependencies change for a local dependency

[LeaVerou]

Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

Suppose we have two adjacent packages, A and B. B has installed A via npm i ../A. When A's dependencies change, B's dependencies script is not triggered.

Expected Behavior

B’s dependencies hook should be triggered whenever its dependencies change, which include A. This works correctly for npm link, so the internal handling for symlinks must be there.

Steps To Reproduce

See above

Environment

• npm: 11.10.0

• System Model Name: Macbook Pro
