Capture the MCP InitializeParams from the client handshake via a receiving middleware and expose them through a new opt-in debug tool get_debug_mcp_init_request. Gated behind the new enable-debug-tools config flag / COLLIBRA_MCP_ENABLE_DEBUG_TOOLS env var (off by default) so the tool stays hidden in normal deployments.
