feat: verify attack-chain nodes against real tool calls
A node claiming something ran must cite a tool_call_id the host issued in the trajectory. A citation absent from the trajectory is invented, so the node is dropped along with its edges; a missing citation counts as invented only when every real ID survived budget fitting, so a trimmed payload cannot silently empty a graph. Judging is skipped where the evidence cannot be enumerated: the process-detail supplement dumps raw event JSON and the messages-table fallback carries no call IDs. Verified citations land in node metadata rather than tool_execution_id, which is foreign-keyed to tool_executions. Also close two smaller holes: fact text can no longer carry the host index delimiters, which would close the block early and spill the remaining index into the system prompt; and the console fact endpoints reject the reserved note/context-* prefix, matching the MCP tool layer.
