Teach the oRPC codegen to split AIP-136 `resource:action` segments so custom
methods nest as clean sibling nodes (apps.byAppId.run) instead of collapsing
the param into a fake static key (apps.appIdRun). Regenerate the committed
oRPC/Zod contract and the split Markdown docs from the new spec.
Update the difyctl call-sites whose wire path or generated method name moved
(describe->get, export->dsl, check-dependencies->dependencies, files/upload->
files, human_input->human-input-forms:submit, role->PATCH) and the Hono mock
server + URL assertions in the CLI test suite.
