Function install_generated_client_extension

src/cli/cli.c:8360–8383

Write a generated client extension module into `path` as a managed block. * * The module is generated from the tool registry rather than shipped (see * src/cli/client_adapter.h), and it goes in as a MARKED BLOCK rather than a * whole-file write: the directory is auto-loaded by the client, so a user may * legitimately keep their own module there, and clobbering it would be the * install routi

 * than a skip, because a silently absent extension is exactly the failure mode
 * that left #616 a no-op for six weeks. */
