initial-setup

To set up the GenVM development environment:

1. Enter the Nix flake environment:

   nix develop .#full
   

2. Initialize git submodules:

   git submodule update --init --recursive --depth 1
   

3. Source environment variables:

   source env.sh
   

   This adds tools/git-third-party to PATH and sources .env if it exists.

4. Update third-party dependencies:

   ./tools/git-third-party/git-third-party update --all
   

   This updates wasmtime, wasm-tools, and applies GenVM-specific patches.

The repository will be ready for development with all dependencies properly configured.
