* feat: add company builder wizard with AI-powered org generation

Adds a new "Build Your Company" step to the onboarding wizard that lets
users describe their business and generates a full agent org structure
using OpenClaw's AI. Includes company plan generation, role deduplication,
agent bootstrap with main-agent reuse, org chart preview, confetti on
success, CSS voxel running-avatar loader, amber theme unification, and
best-effort SSH workspace cleanup.

Made-with: Cursor

* fix: resolve lint errors in CompanyBuilderModal

Replace setState-in-effect pattern with a direct callback, escape
apostrophes in JSX text, and derive org chart hover state without
side effects.
