Add scheduled daily folder backup script
This adds a small standalone script that automates daily backups of a folder using the schedule library.

What it does

• Runs continuously and copies a source folder to a destination directory once a day at a configurable time
• Names each backup by date (e.g. 2026-07-16) so each day's snapshot is kept separately
• Gracefully handles the case where a backup for the current day already exists, instead of throwing an unhandled error

Why
Useful as a lightweight, dependency-light way to keep periodic snapshots of a folder (configs, project files, etc.) without needing a full backup tool or cron setup on systems where that's inconvenient.

How to test

1. pip install schedule
2. Set source_dir and destination_dir at the top of the script
3. Temporarily change the scheduled time to a few minutes from now
4. Run the script and confirm a dated folder appears in destination_dir with the source contents copied

Notes / follow-ups

• No backup rotation/cleanup yet — old backups accumulate over time
• Only supports one source folder per run
• Included a README documenting usage, configuration, and possible future improvements (rotation, compression, CLI config, logging)
