⏱️ fix: Separate MCP GET SSE Stream Timeout from POST and Suppress SDK-Internal Recovery Errors (#11936)
* fix: Separate MCP GET SSE body timeout from POST and suppress SDK-internal stream recovery

- Add a dedicated GET Agent with a configurable `sseReadTimeout` (default 5 min,
  matching the Python MCP SDK) so idle SSE streams time out independently of POST
  requests, preventing the reconnect-loop log flood described in Discussion #11230.
- Suppress "SSE stream disconnected" and "Failed to reconnect SSE stream" errors
  in setupTransportErrorHandlers — these are SDK-internal recovery events, not
  transport failures. "Maximum reconnection attempts exceeded" still escalates.
- Add optional `sseReadTimeout` to BaseOptionsSchema for per-server configuration.
- Add 6 tests: agent timeout separation, custom sseReadTimeout, SSE disconnect
  suppression (3 unit), and a real-server integration test proving the GET stream
  recovers without a full transport rebuild.

* fix: Refactor MCP connection timeouts and error handling

- Updated the `DEFAULT_SSE_READ_TIMEOUT` to use a constant for better readability.
- Introduced internal error message constants for SSE stream disconnection and reconnection failures to improve maintainability.
- Enhanced type safety in tests by ensuring the options symbol is defined before usage.
- Updated the `sseReadTimeout` in `BaseOptionsSchema` to enforce positive values, ensuring valid configurations.

* chore: Update SSE read timeout documentation format in BaseOptionsSchema

- Changed the default timeout value comment in BaseOptionsSchema to use an underscore for better readability, aligning with common formatting practices.
