Subject: [PATCH] refactor(ga): wrap cr_header read in context manager to close
 file handle

open(cr_header, ...).read() on every code_run invocation leaks a file
descriptor until garbage collection. With long sessions this can show
up as ResourceWarning or EBADF under load. Wrap in a with block; net
behavior unchanged.
