fix(@angular/build): copy assets replaced by a rename in watch mode - #34575
Merged

Conversation
When an asset is replaced by renaming another file over it, as editors with atomic save do, the native file watcher on Linux reports the asset as added instead of modified. The incremental build only copied existing assets that were reported as modified, so the output kept the previous contents of the asset. Existing assets reported as added are now copied as well. The new spec disables polling so that the native watcher is used.

Code Review
This pull request updates the application builder to correctly handle asset files replaced by a rename operation (such as an atomic save), which can be reported as added rather than modified by native file watchers. It also adds a corresponding integration test to verify this behavior. There are no review comments, and I have no feedback to provide.
