salesforce-mcp-tunnel-drops-while-container-healthy

The Salesforce MCP tunnel can consistently drop connections (MCP tool failures) even when the underlying container is healthy and responding to direct HTTP. When this happens, use the direct Streamable HTTP bypass: POST /mcp to initialize session, capture Mcp-Session-Id header, then use for subsequent tools/call requests. The 406 response from curl confirms the server is up and expecting proper MCP protocol.
