Fix bd-47f1: bd import now flushes JSONL immediately for daemon visibility

- Changed bd import to call flushToJSONL() instead of markDirtyAndScheduleFlush()
- Ensures daemon FileWatcher detects changes within ~500ms instead of up to 30s
- Fixes race condition where MCP daemon served stale data after CLI import
