Adds a new test that explicitly sets the --watch-fs flag via GRADLE_TASK environment variable to verify the buildpack correctly handles this flag.
Changes the test to set org.gradle.vfs.watch=true in gradle.properties instead of using the --watch-fs command line flag.
Explicitly disable org.gradle.vfs.watch in buildpack gradle.properties to prevent build failures when users have org.gradle.vfs.watch=true in their project gradle.properties, which is incompatible with org.gradle.projectcachedir.

Summary
org.gradle.vfs.watch=truein projectgradle.propertiesto reproduce the incompatibility issueorg.gradle.vfs.watch=false) in the buildpack'sGRADLE_USER_HOME/gradle.propertiesContext
The buildpack sets
org.gradle.projectcachedirfor caching, which is incompatible with Gradle's file system watching feature. When users haveorg.gradle.vfs.watch=truein their projectgradle.properties, builds fail with an incompatibility error.Solution
The buildpack now explicitly sets
org.gradle.vfs.watch=falsein its globalgradle.propertiesconfiguration (GRADLE_USER_HOME/gradle.properties) to override any user project settings and prevent this conflict.GUS-W-19626024
