openclaw - 💡(How to fix) Fix MiniMax sessions: totalTokens stays undefined when model does not return usage data [1 pull requests]

Describe the bug

When a model provider (e.g., MiniMax) does not return usage data in its API response, the session entry totalTokens stays undefined forever. This breaks the memory-flush path and causes redundant compaction loops.

Root Cause

The preflight compaction path in agent-runner-memory.ts already has a fallback (estimatePromptTokensFromSessionTranscript) for when freshPersistedTokens is unavailable. However, the memory-flush path in the same file does not have this fallback.

Proposed fix

Add the same estimatePromptTokensFromSessionTranscript fallback that the preflight compaction path already uses, into the memory-flush path.
