+# Deletes Gradle and Kotlin build output in the main checkout and in every agent worktree (.claude/worktrees/*):
+# each project's build/ (a directory named build next to a build.gradle.kts or settings.gradle.kts), .gradle/configuration-cache
+# and .kotlin. Never looks into export/, libs/, models/, spike/ or "samsung sdk/", and never deeper than four levels.
+# Prints what it removes and the space freed. Waits for the Gradle lock of tools/gradle-serial.sh, so it never deletes
+# under a running build. The orchestrator runs it after removing a worktree or when the disk is low.
