AI linter fixes

Integrates Playwright for end-to-end browser testing with automated web server setup, example smoke tests, and CI-compatible configuration. Introduces Vitest, Testing Library, and related utilities for fast component and unit testing.

Updates scripts, development dependencies, and lockfile to support both test suites. Establishes unified testing commands for local and CI workflows, laying groundwork for comprehensive automated UI and integration coverage.

+# Project Rules
+
+## Testing Policy
+- **Mandatory Tests**: All new features and bug fixes must be accompanied by tests.
+- **Unit/Integration Tests**: Use **Vitest** for testing utilities, hooks, and components.
+- **E2E Tests**: Use **Playwright** for critical user flows (auth, core features).
+- **Coverage**: Aim for high coverage on business logic and critical paths.
+
+## Tech Stack
+- **Framework**: Next.js 15 (App Router)
+- **Language**: TypeScript
+- **Styling**: Tailwind CSS
+- **Database**: PostgreSQL with Drizzle ORM
+- **State Management**: React Query
+
+## Code Style
+- **Functional Components**: Use arrow functions for components.
+- **Types**: strict TypeScript usage (avoid `any`).
+- **Imports**: Use absolute imports (`@/...`).
+

 A simple, privacy-focused habit tracking web app. Track anything, every day.
 
+## 🎯 Vision & Goal
+
+**Goal**: To provide the most frictionless, privacy-respecting tool for users to build consistency in their lives without the barrier of complex sign-ups or data tracking concerns.
+
+**Vision**: A world where self-improvement is accessible to everyone without trading their privacy for it. `trackevery-day` aims to become the standard for "unaccounted" personal tracking, eventually expanding into a broader minimalist "life logger" platform.
+
+## 💼 Business Model
+
+This project operates on a sustainable Open Source model:
+
+1.  **Core Product (Free & Open Source)**: The full application is available for free. Users can self-host or use the public instance.
+2.  **Supporter Tier (Future)**: Optional premium features for power users who want to support development:
+    - Advanced Data Analysis & Trends
+    - Encrypted Cloud Backups
+    - API Access for integrations
+3.  **Donations**: Community support via GitHub Sponsors / Ko-fi to cover hosting costs.

+
+## 🗺️ Roadmap & Tasks
+
+We are building this out in phases. Below is the breakdown of problems into small, actionable tasks.
+
+### Phase 1: Core Refinement (Current Focus)
+
+_Goal: Polish the existing functionality to be feature-complete._
+
+- [ ] **Habit Management**
+  - [ ] Add "Edit Habit" functionality (rename, change type/color).
+  - [ ] Add "Delete/Archive Habit" functionality (UI implementation).
+  - [ ] Implement "Undo Log" (remove accidental logs).
+- [ ] **Visualization**
+  - [ ] Add a "Contribution Graph" (GitHub style) heatmap for each habit.
+  - [ ] Add a simple line chart for "Frequency over Time".
+- [ ] **UX Improvements**
+  - [ ] specific mobile-responsive tweaks for the dashboard grid.
+  - [ ] Add a "Settings" page to manage the token (regenerate, view).
+
+### Phase 2: Data Sovereignty
+
+_Goal: Ensure users truly own their data._
+
+- [ ] **Export/Import**
+  - [ ] Create JSON export handler.
+  - [ ] Create CSV export handler (for spreadsheet analysis).
+  - [ ] Build a "Restore from Backup" feature (JSON import).
+- [ ] **Local-First Enhancements**
+  - [ ] Cache habit data in `localStorage` for faster load times.
+  - [ ] Implement offline queuing for logs when network is unavailable.
+
+### Phase 3: Engagement & Growth
+
+_Goal: Help users stay consistent._
+
+- [ ] **PWA Implementation**
+  - [ ] Add `manifest.json` and service workers.
+  - [ ] Enable "Add to Home Screen" prompt.
+- [ ] **Gamification (Subtle)**
+  - [ ] Visual rewards for hitting streaks (confetti, badges).
+  - [ ] "Levels" based on total consistency score.
+- [ ] **Notifications**
+  - [ ] Browser-based push notifications for reminders (optional).
+
+### Phase 4: Advanced Features (Supporter Tier)
+
+_Goal: Power features for data nerds._
+
+- [ ] **Public Profile** (Optional public shareable link for specific habits).
+- [ ] **API Access** (Generate API keys to log via curl/scripts).
+- [ ] **Webhooks** (Trigger events when a habit is logged).
+
