+Usage:
+  scripts/update_go_license.sh [--check]
+
+Updates Go source files with the project license header.
+
+Rules:
+  - Existing Apache license headers gain:
+      Modified by Arctel.net, 2026
+    directly after the Copyright line.
+  - Go files without a license header receive an Arctel.net Apache header.
+  - //go:build and legacy // +build constraints stay at the top of the file.
+
+Options:
+  --check   Report files that would change and exit non-zero if any are found.
