chore: clean up repo root — remove obsolete files, organize infra into docs/

Remove 21MB Vuexy theme directory (replaced by custom EZSCALE design system),
old session logs, patch notes, screenshots, and discovery artifacts. Move
infrastructure files (Horizon config, install script, VirtFusion API spec,
discover script) into docs/ subdirectories. Update CLAUDE.md reference docs.
