refactor: clean up root directory - move deprecated files to archive

Archive:
- docker-compose.yml, Dockerfile.playwright
- scripts/ (legacy test scripts)
- docs/, .test/ (old documentation and tests)
- IMPROVEMENT_PROPOSAL.md (superseded by .kilo/)
- BROWSER_VISIBILITY.md, README.Docker.md
- cleanup-packages.sh, fix-permissions.sh, install-apaw.sh

Keep in root:
- .kilo/ (active system)
- .claude/ (Claude Code runtime)
- AGENTS.md (agent reference)
- README.md (main documentation)
- src/ (utility code)
- package.json, tsconfig.json (project config)
