feat(phase-0): setup Docker Compose with TypeScript monorepo structure

- Create monorepo structure with apps/ and packages/
- Add Docker Compose for api, web, db, redis, worker services
- Migrate existing Express.js logic to TypeScript with 100% backward compatibility
- Preserve all existing API endpoints (/api/track, /api/v1/track) with identical behavior
- Setup development environment with hot reload and proper networking
- Add comprehensive TypeScript configuration with path mapping
- Include production-ready Dockerfiles with multi-stage builds
- Maintain existing rate limiting (100 req/hour/IP) and response formats
- Add health checks and graceful shutdown handling
- Setup Turbo for efficient monorepo builds and development

+# Redirect Intelligence v2
+
+A comprehensive URL redirect tracking and analysis platform built with Node.js, React, and PostgreSQL.
+
+## 🚀 Quick Start
+
+### Prerequisites
+
+- Node.js 20+
+- Docker & Docker Compose
+- Git
+
+### Development Setup
+
+1. **Clone and setup environment:**
+   ```bash
+   git clone <your-repo-url>
+   cd redirect-intelligence-v2
+   cp .env.example .env
+   ```
+
+2. **Start development environment:**
+   ```bash
+   npm run dev
+   ```
+
+   This will start all services:
+   - API: http://localhost:3333
+   - Web: http://localhost:3000
+   - PostgreSQL: localhost:5432
+   - Redis: localhost:6379
+
+3. **Access the application:**
+   - Main App: http://localhost:3000
+   - API Docs: http://localhost:3333/api/docs
+   - Health Check: http://localhost:3333/health
+
+## 📋 Project Structure
+
+```
+├── apps/
+│   ├── api/          # Express.js API server (TypeScript)
+│   ├── web/          # React frontend (Chakra UI)
+│   └── worker/       # BullMQ background worker
+├── packages/
+│   ├── database/     # Prisma schema & migrations
+│   └── shared/       # Shared types & utilities
+└── docker-compose.yml
+```
+
+## 🔄 Backward Compatibility
+
+All existing API endpoints are preserved:
+
+- `POST /api/track` (legacy)
+- `POST /api/v1/track` 
+- `GET /api/v1/track`
+
+Rate limiting: 100 requests/hour per IP (unchanged)
+
+## 🛠️ Development Commands
+
+```bash
+# Start all services
+npm run dev
+
+# Individual services
+npm run dev:api
+npm run dev:web
+
+# Database operations
+npm run db:migrate
+npm run db:studio
+npm run db:seed
+
+# Build & test
+npm run build
+npm run test
+npm run lint
+```
+
+## 📖 API Documentation
+
+Visit http://localhost:3333/api/docs for interactive API documentation.
+
+## 🔍 Current Status
+
+**Phase 0: Complete** ✅
+- Docker Compose setup
+- TypeScript migration
+- Monorepo structure
+- Backward compatibility preserved
+
+**Next: Phase 1** - PostgreSQL + Prisma + Authentication
+
+## 🧪 Testing
+
+Test the backward compatibility:
+
+```bash
+# Test legacy endpoint
+curl -X POST http://localhost:3333/api/track \
+  -H "Content-Type: application/json" \
+  -d '{"url": "github.com"}'
+
+# Test v1 endpoint
+curl -X POST http://localhost:3333/api/v1/track \
+  -H "Content-Type: application/json" \
+  -d '{"url": "github.com", "method": "GET"}'
+```

+# Redirect Intelligence — v2 Update (Chakra UI, Admin + Users, Postgres)
+
+## 0) Goals & Strategy
+
+- **Keep Node/Express** to minimize rewrite risk and preserve existing routes/limits/options (GET/POST `/api/v1/track`, legacy `/api/track`, 100 req/hr IP rate-limit, UA presets, SSL extraction, response-body truncation) [Comprehensive App Doc].
+- **Add Postgres** via Prisma for users/orgs/projects/history/reports/jobs.
+- **Upgrade UI to Chakra UI** with a modular app shell, light/dark, accessible components.
+- **Expand analysis** to include robots/meta/canonical/mixed content and optional JS redirects; add export (MD/PDF), bulk jobs, API keys, monitoring—carried over from the earlier plan.
+
+---
+
+## 1) Tech Stack (final)
+
+- **Backend:** Node.js 20, Express (TS), **Prisma + PostgreSQL**, Zod (validation), **BullMQ + Redis** (bulk & monitoring), **Axios/undici** (HTTP), **Playwright** (optional JS redirects), **Puppeteer** (PDF export), `rate-limiter-flexible` (limits), `jsonwebtoken`/`jose` (auth).
+- **Frontend:** React + TypeScript, **Chakra UI**, TanStack Query, React Router, Mermaid (client render) + server render for PDFs.
+- **Auth:** Email/password (argon2), organization membership, roles (owner/admin/member), HttpOnly cookie sessions.
+- **Billing (Phase later):** Stripe.
+- **Packaging:** Docker Compose (api, web, db, redis, worker).
+
+---
+
+## 2) Data Model (PostgreSQL via Prisma)
+
+**Core tables**
+
+- `users(id, email unique, name, password_hash, created_at, last_login_at)`
+- `organizations(id, name, plan, created_at)`
+- `org_memberships(id, org_id fk, user_id fk, role enum(owner|admin|member))`
+- `projects(id, org_id fk, name, settings_json, created_at)`
+- `checks(id, project_id fk, input_url, method, headers_json, user_agent, started_at, finished_at, status enum(ok|error|timeout|loop), final_url, total_time_ms, report_id nullable)`
+- `hops(id, check_id fk, hop_index, url, scheme, status_code, redirect_type enum(http_301|302|307|308|meta_refresh|js|final|other), latency_ms, content_type, reason, response_headers_json)`
+- `ssl_inspections(id, check_id fk, host, valid_from, valid_to, days_to_expiry, issuer, protocol, warnings_json)`
+- `seo_flags(id, check_id fk, robots_txt_status, robots_txt_rules_json, meta_robots, canonical_url, sitemap_present, noindex bool, nofollow bool)`
+- `security_flags(id, check_id fk, safe_browsing_status, mixed_content enum(none|present|final_to_http), https_to_http bool)`
+- `reports(id, check_id fk, markdown_path, pdf_path, created_at)`
+- `bulk_jobs(id, project_id fk, upload_path, status enum(queued|running|done|error), progress_json, created_at, completed_at)`
+- `api_keys(id, org_id fk, name, token_hash, perms_json, rate_limit_quota, created_at)`
+- `audit_logs(id, org_id fk, actor_user_id fk, action, entity, entity_id, meta_json, created_at)`
+
+**Indexes**
+- `checks(project_id, started_at desc)`, `hops(check_id, hop_index)`, `api_keys(token_hash)`
+
+---
+
+## 3) API (preserve current + extend)
+
+**Keep existing behavior**
+- `POST /api/v1/track`, `GET /api/v1/track` (query param mode), legacy `/api/track`, rate-limit (100/hr/IP), UA options, timing, SSL extraction, response truncation & metadata.
+
+**New (MVP+)**
+- `POST /api/v1/checks` (alias of `track` that persists history & returns `check_id`)
+- `GET /api/v1/checks/:id` (check + hops + ssl + seo + security + diagram)
+- `POST /api/v1/reports/:check_id/export` (`{format: md|pdf}`)
+- `GET /api/v1/projects/:id/checks` (paginated history, filters)
+- `POST /api/v1/bulk-jobs` (CSV upload), `GET /api/v1/bulk-jobs/:id` (progress, download bundle)
+- `POST /api/v1/auth/login`, `POST /api/v1/auth/logout`, `GET /api/v1/auth/me`
+- `POST /api/v1/users` (admin), `GET/PUT /api/v1/users/:id`
+- `POST/GET/DELETE /api/v1/api-keys` (org-scoped), public namespace: `POST /public/checks`, `GET /public/checks/:id` with `x-api-key`
+
+---
+
+## 4) Analysis Pipeline (Node)
+
+**HTTP chain (non-JS) now**
+- Manual redirect following with Axios/undici (turn off auto-follow to record hops), keep per-hop timeouts, normalize URLs, loop set, capture headers. Preserves existing behavior.
+
+**Additions**
+- **Meta refresh** parse when 200 HTML with `<meta http-equiv="refresh">`.
+- **SEO/Security**: fetch/parse robots.txt; parse `<meta name="robots">`, canonical; detect HTTP→HTTPS / HTTPS→HTTP; scan final HTML for `http://` subresources = mixed content.
+- **Optional JS redirects** (phase later): Playwright worker with hard caps; record `window.location` changes as `js` hops.
+
+---
+
+## 5) Exports
+
+- **Markdown** via Nunjucks/Jinja-like templates in Node.
+- **PDF** via Puppeteer (server-side render of a report page); embed Mermaid SVG graph; org branding for paid tiers.
+
+---
+
+## 6) Frontend — Chakra UI
+
+**App Shell (Chakra)**
+- Header (org/project switcher, theme toggle), left Nav (Dashboard, Checks, Bulk, Projects, API, Monitoring, **Admin**), content area with responsive grid.
+
+**Key Screens**
+1) **Home / New Check**
+2) **Check Detail**: Chain Table + Mermaid Diagram, flags, export.
+3) **History (Project)**
+4) **Bulk Jobs**
+5) **Monitoring**
+6) **API**
+7) **Admin Panel**
+
+**Chakra Components**
+- `Container`, `Grid`, `Card`, `Table`, `Badge`, `Tabs`, `Accordion`, `Alert`, `Stat`, `FormControl`, `Select`, `Drawer`, `Modal`, `Menu`, `Progress`, `Skeleton`, `Toast`.
+
+---
+
+## 7) Security & Limits
+
+- Preserve **100/hr/IP** default limit on public endpoints; add per-org/user buckets for authenticated usage.
+- HttpOnly cookie sessions; CSRF on mutations; password hashing (argon2).
+- Redact sensitive headers from persistence/logs.
+
+---
+
+## 8) Phased Build Plan (Cursor-Ready)
+
+### Phase 0 — Repo & Env (Dockerized)
+### Phase 1 — Postgres + Prisma + Auth
+### Phase 2 — Persisted Checks (Non-JS Chain)
+### Phase 3 — SSL/SEO/Security Flags
+### Phase 4 — Chakra UI Upgrade Complete
+### Phase 5 — Exports (MD & PDF)
+### Phase 6 — Bulk CSV + Worker
+### Phase 7 — Request Options UI
+### Phase 8 — API Keys + Public API + Quotas
+### Phase 9 — Optional JS Redirects
+### Phase 10 — Monitoring & Alerts
+### Phase 11 — Admin Panel
+### Phase 12 — Billing (Stripe)
+### Phase 13 — Hardening & Perf
+
+---
+
+## 9) UI Map (Chakra)
+
+- **Layout:** AppShell (Sidebar, Header, Main).
+- **Home/New Check:** Input, Select, Drawer for headers.
+- **Detail:** Tabs, Accordion for hops, Badges for flags, Stats, Buttons.
+- **History:** Table with filters.
+- **Bulk:** Dropzone, Progress, job list.
+- **Admin:** Table for users, Modal invite, Select roles, Form for org & settings.
+
+---
+
+## 10) Back-Compat & Migration
+
+- Keep existing **endpoint semantics** and response shape for `/api/v1/track` and legacy `/api/track`.
+
+---
+
+## 11) Acceptance & KPIs
+
+- Single URL (non-JS) median end-to-end < 1.2s; p95 < 3s.
+- Meta refresh detection ≥ 99% test corpus.
+- PDF export success ≥ 99%/1k reports.
+- Bulk throughput ≥ 50 URLs/s with 5 workers.
