…meter name collisions

- Updated the analyze method in ServicesData to reserve the service package name, ensuring it does not conflict with parameter names in generated code.

Tests: all unit tests pass.

…\n- SSE: emit protocol errors as SSE events; normalize error messages; no leaks (one-shot stream).\n- WS: fix request vs notification, generic error messages, empty-method handling.\n- HTTP: restore proper parse-error envelopes for invalid JSON.\n- Harness: support null/numeric IDs and explicit id presence for WS; honor JSONRPC field on SSE.\n- Scenarios: add WS/SSE protocol edge cases and mixed HTTP/JSON-RPC cases.\n- Templates: clean handler wiring (avoid recursion), correct SSE mount/init.\n\nAll JSON-RPC integration tests pass locally.

…ke executor and executor options private; Runner remains public.\n- update Runner to use private executor via factory/ctor.\n- minor formatting cleanups.\n\nAll integration tests pass.

…and emit GRPC() in DSL when set

…ndpoint generation; parse in MethodInfo and conditionally emit GRPC() in DSL; rename mixed scenario method to grpc_process

…c_ methods are present; auto-assign grpc port; detect readiness

…erver; only pass Svc to HTTP handler

…transports; make RawResponse.ID any; websocket client: treat missing id as nil and backfill via IDToString; integration tests: add numeric envelope id scenarios; idmap: payload/result use string id + string request_id; generator: only add id/request_id for idmap methods; fix echo impl for idmap; align scenarios to types

…llocate slices in server_data

… keep JSON-RPC endpoints; keep single-line handler calls
