Replace the NO-OP importToJSONLWithStore() stub with full implementation: - Reads and parses JSONL file line by line using bufio.Scanner - Uses importIssuesCore() with auto-collision resolution enabled - Integrates with existing import infrastructure - Fixes PRIMARY root cause of bd-160 multi-clone sync failure The daemon now properly imports remote changes pulled from git instead of ignoring them, allowing databases to converge across clones.
