Removed outdated binary files and the `run_500_times.bat` script, which automated repetitive runs of `URLNotesGrabberCORE`. The batch script is no longer needed or has been replaced.
Added `verify-db-schema.sql`, a new script to verify and align the SQLite database schema (`TL.db`) with the application's expected schema. The script includes:
- A verification section to identify missing/extra columns or tables.
- An optional fix section with `ALTER TABLE` statements to add missing columns.
The SQL script ensures database compatibility while preserving data integrity and avoiding destructive operations.
