feat: initial scaffold kanban_cpp v0.1.0

C++ ImGui kanban for steering LLM agents. Six panels (Board, Calendar, Dashboard, Agent runs, Worktrees, DoD inspector) wired to registry functions http_request, kpi_card, sparkline, agent_runs_timeline, dod_evidence_panel. Backend Go on :8403 (independent operations.db from kanban_web).
