resourceDependencies always empty — external templateUrl/styleUrls not reported

[brandonroberts]

transformAngularFile does not report external templateUrl/styleUrls files as resource dependencies.

Repro

Compile a component with templateUrl: './x.html' — result.dependencies comes back [].

Expected

External resource paths are listed so the Vite plugin can register them as watch dependencies.

Impact

HMR/rebuild silently misses edits to external .html/.css files.
