* feat: add DeepWiki MCP server at project level * feat(omp): poll context window usage during active turns OMP agents previously reported context window usage only at turn completion, unlike Claude and Codex which stream live updates. Add a periodic poll (3s interval) of getSessionStats() that emits usage_updated events while a turn is active, so the client context window meter updates in real-time. * clear context usage poll timer before scheduling next interval * chore: remove .omp/ directory * fix(omp): make live usage polling lifecycle-safe OMP exposes live usage through a stats request rather than stream events. Keep polling scoped to active turns, suppress unchanged snapshots, and invalidate stale completion reads across interrupts, new turns, and session shutdown. --------- Co-authored-by: Mohamed Boudra <boudra.moha@gmail.com>
