Summary

Fix status context rendering when session token totals are stale.

When totalTokensFresh=false, status previously fell back to inputTokens + outputTokens, which can overstate context usage and report misleading values like 299k/200k (149%).

This change avoids that fallback for stale totals and reports unknown context occupancy unless fresh totals (or transcript usage) are available.

Changes

• src/auto-reply/status.ts
  • Stop inferring totalTokens from input+output when totalTokensFresh is explicitly false.
  • Preserve transcript-usage override behavior so runtime can still show a concrete usage value when available.
• src/auto-reply/status.test.ts
  • Add regression test covering totalTokensFresh=false to ensure status shows unknown context usage instead of synthetic input+output usage.

User impact

• Prevents false alarms that auto-compaction is broken.
• Makes /status context line semantically accurate in stale-token states.

Validation

• pnpm vitest run src/auto-reply/status.test.ts
• Result: all tests passed locally.

Notes

This is a display/accounting correctness fix; it does not alter compaction trigger behavior itself.
