fix: Update .gitignore and remove dev files from repository

Remove development and investigation files that shouldn't be in repo:
- Kate editor swap files (*.swp, *.kate-swp)
- Discord development folder (contains credentials)
- Development investigation scripts (db_investigation.sh, etc.)
- Configuration files (docker-compose.dev.yml)

Note: Files removed from git but kept locally (rm --cached)
Files are still present in working directory but won't be tracked
