Add comprehensive integration tests for auto-import collision detection (bd-401)

- Created autoimport_collision_test.go with 10 new test scenarios
- Added helper functions: createTestDBWithIssues, writeJSONLFile, captureStderr
- Tests cover: multiple collisions, all collisions, exact matches, hash fast path,
  parse errors, empty JSONL, new issues only, field conflicts, JSONL not found
- Achieved 75.3% coverage of autoImportIfNewer function
- All 17 auto-import tests passing in ~1 second
- Tests verify collision auto-remapping behavior

Closes bd-401
