Function build 

pub fn build(config: BuildConfig) -> Result<BuildResult, BuildError>

Build a LOGOS project.

Compiles the project specified in config through the full build pipeline:

1. Load and validate the manifest
2. Compile LOGOS source to Rust
3. Generate a Cargo project with runtime dependencies
4. Run cargo build

The entry point is determined from the manifest’s package.entry field, with a .md extension fallback if the .lg file doesn’t exist.

Errors

Returns an error if:

• The manifest cannot be loaded
• The entry point file doesn’t exist
• LOGOS compilation fails
• Cargo build fails
