+install_aw_linux_client.sh now requires the Rust planner for safe default runs.
+Build it first:
+  cd adk-rust && cargo build --release -p aw-linux-install
+
+Safe dry-run:
+  scripts/install_aw_linux_client.sh --json
+
+Explicit install:
+  scripts/install_aw_linux_client.sh --apply
+
+Old shell install:
+  scripts/install_aw_linux_client.sh --apply-legacy
+EOF
+    exit 2
