Ahmed Ibrahim 0e78ce80ee [3/4] Add executor-backed RMCP HTTP client (#18583)
### Why
The RMCP layer needs a Streamable HTTP client that can talk either
directly over `reqwest` or through the executor HTTP runner without
duplicating MCP session logic higher in the stack. This PR adds that
client-side transport boundary so remote Streamable HTTP MCP can reuse
the same RMCP flow as the local path.

### What
- Add a shared `rmcp-client/src/streamable_http/` module with:
  - `transport_client.rs` for the local-or-remote transport enum
  - `local_client.rs` for the direct `reqwest` implementation
  - `remote_client.rs` for the executor-backed implementation
  - `common.rs` for the small shared Streamable HTTP helpers
- Teach `RmcpClient` to build Streamable HTTP transports in either local
or remote mode while keeping the existing OAuth ownership in RMCP.
- Translate remote POST, GET, and DELETE session operations into
executor `http/request` calls.
- Preserve RMCP session expiry handling and reconnect behavior for the
remote transport.
- Add remote transport coverage in
`rmcp-client/tests/streamable_http_remote.rs` and keep the shared test
support in `rmcp-client/tests/streamable_http_test_support.rs`.

### Verification
- `cargo check -p codex-rmcp-client`
- online CI

### Stack
1. #18581 protocol
2. #18582 runner
3. #18583 RMCP client
4. #18584 manager wiring and local/remote coverage
