- Renamed the internal URL protocol handler from `pi` to `omp` and updated the router export/import wiring to use `OmpProtocolHandler` with the `omp://` scheme. - Updated embedded documentation link rendering and related validation/error messages in the protocol handler to reference `omp://` URLs. - Adjusted tests and prompt/docs references so `read` examples and harness documentation guidance now use the renamed `omp://` scheme.
