refactor: reorganize project structure — consolidate Docker files, clean root

- Delete temp files: _tmp_analysis.py, nul, dashboard_screenshot.png
- Move ea/ to archive/ea/ (deprecated)
- Move 12 Docker helper scripts (.bat/.sh) to docker/scripts/
- Move 5 Docker docs to docker/docs/
- Move .env.docker.example, requirements-docker.txt to docker/
- Update all scripts with cd to project root for correct path resolution
- Update all doc references to new paths
- Update .gitignore with bot.pid, bot_output.log, *.png patterns
- Update CLAUDE.md, README.md directory trees

Root reduced from ~40 files to 12 essential files.
