cleanup: Remove unused files and fix ETHOS violations
Remove unused generation scripts (not referenced):
- scripts/generate-keypair.go (unused manual utility)
- cmd/tools/keygen/ (unused utility, clutters cmd structure)
Remove root-level dev files (clutter):
- restart_and_fix.sh (dangerous: wipes database)
- test_install_commands.sh (development only)
- test-binary (compiled artifact)
- sudo (third-party tool)
- scanning_ux_summary.txt (dev notes)
Fix ETHOS violations in build-secure-agent.sh:
- Remove emojis (🔨, ✅, ℹ️)
- Replace with proper format: [INFO] [build] ...
Cleanup based on definitive code forensics.
Impact: Cleaner repository, ETHOS-compliant, no functional loss.
