chore: organize backup files into dated directory structure

- Consolidated all .bak.* files from bot/ directory into backups/2025-12-07/
- Moved unused autonomous_wip.py to backups (verified not imported anywhere)
- Relocated old .bot.bak.80825/ backup directory into backups/2025-12-07/old-bot-bak-80825/
- Preserved autonomous_v1_legacy.py as it is still actively used by autonomous.py
- Created new backups/ directory with date-stamped subdirectory for better organization
