feat: Sprint 5 — AI insights, webhooks/Slack, PWA, performance monitoring

AI-Powered Insights (G9): - Rule-based anomaly detection: budget burn rate, staffing gaps, utilization, timeline overruns across all active projects - AI narrative generation via existing Azure OpenAI integration - Cached in project dynamicFields to avoid regeneration - New /analytics/insights page with anomaly feed + project summaries - Sidebar nav: "AI Insights" under Analytics Webhook System + Slack (G10): - Webhook model in Prisma (url, secret, events, isActive) - HMAC-SHA256 signed payloads with 5s timeout fire-and-forget dispatch - Slack-aware: routes hooks.slack.com URLs through Slack formatter - 6 events integrated: allocation.created/updated/deleted, project.created/ status_changed, vacation.approved - Admin UI: /admin/webhooks with CRUD, test button, event checkboxes - webhook router: list, getById, create, update, delete, test PWA Support (G11): - manifest.json with standalone display, brand-colored icons (192+512px) - Service worker: cache-first for static, network-first for API, offline fallback - ServiceWorkerRegistration component with 60-min update checks - InstallPrompt banner with 30-day dismissal memory - Apple Web App meta tags + viewport theme color Performance Monitoring (A15): - Pino structured logging (JSON prod, pretty dev) via LOG_LEVEL env - tRPC logging middleware on all protectedProcedure calls - Request ID (UUID) per call for log correlation - Slow query warnings (>500ms) at warn level - GET /api/perf endpoint: memory, uptime, SSE connections, node version Fix: renamed scenario.apply to scenario.applyScenario (tRPC reserved word) Co-Authored-By: claude-flow <ruv@ruv.net>
