fix: update .gitignore to cover all bot/memory subdirs, untrack runtime data

- Change bot/memory/*.json to bot/memory/** to properly ignore all
  subdirectories (dms/, dm_reports/, profile_pictures/)
- Untrack bot/memory/ files from index (DMs, profile pics, dm reports)
- Untrack cheshire-cat discord_bridge __pycache__/*.pyc from index
- These files are runtime/user data that should never be in version control
