Adds a defensive tool-pair-validator hook that runs as the final step in the messages transform pipeline. When compaction or context-window recovery removes user messages containing tool_result blocks without removing the preceding assistant message with tool_use blocks, this validator detects the mismatch and either: 1. Injects missing tool_result parts into the next user message, or 2. Creates a synthetic user message with placeholder tool_results This prevents Anthropic API errors like 'tool_use ids found without tool_result blocks immediately after'. Fixes #3014
