Update ADK configuration and add local Docker testing setup

[MrOrz]

Summary

This PR bundles several improvements to the local development experience and ADK integration.

✅ Add docker-compose.yml for local builds

Adds a docker-compose.yml that builds both services from source and wires them together, making it easy to spin up the full stack locally and validate the Docker build before deployment:

• frontend — builds from the root Dockerfile, exposed on port 3000, configured with ADK_URL pointing to the backend service
• backend — builds from adk/Dockerfile, exposed on port 8000, reads secrets from adk/cofacts_ai/.env via env_file, and includes a health check so the frontend only starts once ADK is ready

🐛 Fix ADK app name (underscore vs. hyphen)

ADK requires the app name to match the Python module directory name, which uses underscores. Changed cofacts-ai → cofacts_ai in:

• src/lib/adk.ts
• src/routes/api/sessions.ts
• src/routes/api/sessions.$sessionId.ts

📦 Upgrade google-adk (lockfile update)

Updated adk/uv.lock to pull in the latest google-adk and its transitive dependencies.

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request streamlines the development and testing process by updating the ADK application's naming convention and introducing a comprehensive local Docker setup. These changes aim to provide a more consistent and isolated environment for developers, making it easier to build, run, and test the application locally, mirroring the CI/CD pipeline.

Highlights

• ADK Configuration Update: The ADK application name was standardized from "cofacts-ai" to "cofacts_ai" across the codebase and file paths to ensure consistency.
• Local Docker Testing Setup: A new local Docker testing environment was introduced using docker-compose.yml and adk/.dockerignore, enabling developers to build and test frontend and backend Docker images locally.
• Documentation Enhancement: The README.md was updated to include detailed instructions for the new local Docker testing environment and clarified ADK server URLs for development.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

This pull request introduces a local Docker testing setup using Docker Compose, which is a significant improvement for the development workflow. It also refactors the ADK application name from cofacts-ai to cofacts_ai for consistency with Python package naming conventions, and updates the ADK server command. The changes are well-implemented. I have a couple of minor suggestions to improve the documentation and the new Docker Compose configuration for consistency.
