fix(cli): preserve intermediate directories when resolving nested file paths (#1607)

Fixes component installation paths for custom registries with additional
path levels. Previously, only the last segment of the common root was
preserved, causing intermediate directories to be lost.

Example:
- Before: components/ai-elements/artifact/Artifact.vue → artifact/Artifact.vue
- After: components/ai-elements/artifact/Artifact.vue → ai-elements/artifact/Artifact.vue

The function now uses the component alias from config to correctly resolve
paths for any custom registry structure, not just the default "components"
directory.
