[ANOLISA] bug(cosh-ng): HTTP MCP misroutes server requests

## Observed symptom bug(cosh-ng): HTTP MCP misroutes server requests # bug(cosh-ng): HTTP MCP misroutes server requests with a matching numeric ID ## Summary The Streamable HTTP SSE reader and the legacy HTTP+SSE reader compare an incoming message's numeric `id` with the outstanding client request before checking whether the message is a server request (`method` + `id`). A valid server `ping` with the same numeric ID is therefore passed to `extract_result`, which rejects it as `MCP response to 'initialize' has no result` (or `tools/list`). The ping is not answered, and initialization or tool discovery fails. The stdio transport already dispatches server requests before matching responses. Both HTTP transports have the same defect and should be fixed togeth ## Literal error text ``` s numeric ``` ## Environment GitHub agentic-os-org/ANOLISA #3592 ## Trigger / context # bug(cosh-ng): HTTP MCP misroutes server requests with a matching numeric ID ## Summary The Streamable HTTP SSE reader and the legacy HTTP+SSE reader compare an incoming message's numeric `id` with the outstanding client request before checking whether the message is a server request (`method` + `id`).
