## Current Behavior
In ng-packagr-lite watch mode, all output files are written to disk on
every incremental build regardless of whether their content actually
changed. This causes downstream watchers (like Vite) to see all files as
"changed" and trigger full rebuilds instead of incremental ones.
## Expected Behavior
Only files with changed content should be written to disk during
incremental builds in watch mode. This allows downstream watchers to
properly detect which files actually changed and perform efficient
incremental rebuilds.
