Update README

Update the project README.md with comprehensive documentation.

1. Analyze Project Structure and State

   • List the files in the root directory to identify the project type (Node.js, Python, etc.).
   • Read key configuration files if they exist (e.g., package.json, tsconfig.json, shopify.app.toml, fly.toml, requirements.txt, Gemfile, cargo.toml).
   • List the contents of valid source directories (e.g., app/, src/, lib/, components/) to understand the architecture.

2. Read Existing Documentation

   • Read the current README.md to preserve any manual sections or specific instructions the user has added.
   • If available, read .agent/brain/task.md or implementation_plan.md to understand recent changes and current features (optional, do not fail if missing).

3. Generate/Update README.md

   • Rewrite README.md to include the following sections (adapt as necessary for the project type):
     • Project Title & Description: A clear summary of what the project does.
     • Features: A list of key features inferred from the codebase and installed packages/skills.
     • Tech Stack: Languages, frameworks, and key libraries used.
     • Prerequisites: Tools needed to run the project (Node, Python, Docker, etc.).
