The previous code had two bugs:
1. Double 'file:' prefix when path was ':memory:'
2. Two '?' separators instead of proper '?...&...' syntax
This caused SQLite errors: 'no such cache mode: shared?_pragma=...'
Fixed by:
- Building connStr directly for :memory: case with proper syntax
- Using '&' to chain query parameters
- Handling filepath.Abs() only for real files, not :memory:
