bd export currently silently overwrites issues.jsonl even when the
database is stale (older than the JSONL file). This causes data loss
in multi-agent workflows.
Real incident from vc project:
- Agent A created 4 discovery epics and exported
- Agent B had stale database and exported, removing those epics
- Required manual recovery
Proposed fix: Check database freshness before export, similar to
VC's ValidateDatabaseFreshness(). Require --force to override.
Priority P1: Silent data loss in common multi-agent scenario.
