re-raise exceptions in the _handle_json_response

[jdchawla29]

Note

Medium Risk
Changes runtime monkey-patching of MCP transport internals; behavior shifts from swallowed errors to raised exceptions, which may affect retry/error flows in production if upstream expectations differ.

Overview
Fixes a hang in MCP streamable HTTP requests by patching StreamableHTTPTransport._handle_json_response to log and re-raise exceptions from response.aread() and JSON parsing instead of sending raw exceptions into the read stream.

Registers this new patch in apply_all_patches() so it is applied alongside the existing streamable HTTP error-handling patch.
