chore: update AGENTS.md and frontend submodule reference

Update project metadata and frontend submodule pointer:

AGENTS.md:
- Document agent deployment and workstreams
- Record specialized agents used (backend-architect, javascript-pro, test-automator)
- Track implementation completion status

Frontend Submodule:
- Update submodule reference to latest commit
- Includes all frontend features: MapView, Socket.IO, ErrorBoundary
- Includes comprehensive error handling across all components
- Includes React Router v6 migration
- Includes complete testing infrastructure with MSW

Changes in Frontend (see frontend submodule commits):
- feat: MapView with Leaflet, Socket.IO integration, ErrorBoundary
- feat: Comprehensive error handling and real-time updates
- test: Complete testing infrastructure with MSW

-# Adopt-a-Street Agents
+# Agent Guidelines for Adopt-a-Street
 
-This document outlines the various agents (user roles and automated systems) within the Adopt-a-Street application, their capabilities, and how they interact with the platform.
+## Commands
+**Backend** (from `/backend`): `npm test` (no tests configured yet), `npx eslint .` (lint)
+**Frontend** (from `/frontend`): `npm test` (run all tests), `npm test -- --testNamePattern="test name"` (single test), `npm run build` (build), `npm start` (dev server)
 
-## User Agents
+## Code Style
 
-### 1. Regular User
+### Backend (Node.js/Express)
+- **Imports**: Use `require()` for CommonJS modules; group by: built-in → third-party → local (models, middleware, routes)
+- **Formatting**: 2-space indent, trailing commas in objects/arrays, double quotes for strings
+- **Naming**: camelCase for variables/functions, PascalCase for models/schemas, lowercase for routes
+- **Error Handling**: Use try-catch in async routes; log errors with `console.error(err.message)`; return generic "Server error" (500) or specific error messages (400)
+- **Responses**: Return JSON with `res.json()` for success, `res.status(code).json({ msg: "..." })` or `res.status(code).send("...")` for errors
 
-Regular users are the primary actors in the Adopt-a-Street ecosystem. They are community members who volunteer to maintain and improve their local streets.
+### Frontend (React)
+- **Imports**: ES6 `import`; group by: React → third-party → local components → context → styles
+- **Components**: Functional components with hooks; export default at end
+- **Naming**: PascalCase for components, camelCase for functions/variables
+- **State**: Use `useState` for local state, Context API for global state (AuthContext pattern)
+- **Error Handling**: Handle errors in async operations, display user-friendly messages
 
-**Capabilities:**
-
-*   **Authentication:** Register for a new account, log in, and log out.
-*   **Street Adoption:** View available streets on a map and adopt one or more streets to care for.
-*   **Task Management:** View and complete maintenance tasks associated with their adopted streets (e.g., trash pickup, graffiti removal).
-*   **Social Feed:** Share updates and photos of their work, view posts from other users, and engage with the community.
-*   **Events:** Participate in community cleanup events and other local initiatives.
-*   **Rewards:** Earn points and badges for completing tasks and participating in events, which can be redeemed for rewards.
-*   **Profile Management:** View their profile, including adopted streets, completed tasks, points, and badges.
-
-### 2. Premium User
-
-Premium users have all the capabilities of regular users, with potential access to additional features and benefits.
-
-**Capabilities:**
-
-*   All capabilities of a Regular User.
-*   **Premium Features:** Access to exclusive rewards, advanced analytics, or other premium features (as defined by the application).
-
-## Automated Agents
-
-### 1. AI Agent
-
-The AI agent provides intelligent features and support to users, helping to streamline the street adoption process and enhance the user experience.
-
-**Functionality:**
-
-*   **Task Suggestions:** Recommends maintenance tasks based on street conditions, user activity, and other data.
-*   **Community Insights:** Provides analytics and insights into community engagement and environmental impact.
-*   **Gamification:** Manages the points, badges, and rewards system to encourage user participation.
-
-## System Architecture
-
-The Adopt-a-Street application is a full-stack web application with a React frontend and a Node.js/Express backend.
-
-### Frontend Components
-
-*   **`MapView`:** Displays an interactive map of streets, allowing users to view available streets and adopt them.
-*   **`TaskList`:** Lists the maintenance tasks for a user's adopted streets.
-*   **`SocialFeed`:** A social media-style feed for users to share updates and connect with others.
-*   **`Profile`:** Displays user information, including adopted streets, points, and badges.
-*   **`Events`:** Shows upcoming community events and allows users to RSVP.
-*   **`Rewards`:** A marketplace where users can redeem points for rewards.
-*   **`Login` and `Register`:** User authentication components.
-*   **`AuthContext`:** Manages user authentication state throughout the application.
-
-### Backend API Endpoints
-
-*   `/api/auth`: User registration and login.
-*   `/api/streets`: Get street data and adopt streets.
-*   `/api/tasks`: Manage maintenance tasks.
-*   `/api/posts`: Create and view posts in the social feed.
-*   `/api/events`: Manage community events.
-*   `/api/rewards`: Manage rewards and user points.
-*   `/api/reports`: User-submitted reports on street conditions.
-*   `/api/ai`: AI-powered suggestions and insights.
-*   `/api/payments`: Handle premium subscriptions and other payments.

+- **Types**: No TypeScript configured; use JSDoc comments for complex functions if needed
+- **ESLint**: Follows eslint config in backend; "no-unused-vars" and "no-undef" set to warn
