• f7bc0b4: feat(mcp): expose statusCode, url, and responseBody on MCPClientError for HTTP transport failures

  MCPClientError now carries structured HTTP context when it originates from the
  streamable HTTP transport. This lets downstream consumers (e.g. agent frameworks
  that need to decide whether to fall back from streamable HTTP to legacy SSE
  transport per the MCP spec) branch on the actual response status without parsing
  the error message string.

  Fields are optional — they remain undefined for stdio transport errors and for
  non-response failures (network errors, aborts).
