Phenotyper Core — compiler library for the Phenotyper structural artifact definition language.

This crate implements the full compilation pipeline:

• Lexer: Tokenization of .pht and .md sources
• Parser: Rustemo-based parser producing a span-annotated AST
• AST: Surface syntax tree data types
• Symbol table: Name collection and resolution
• IR: Normalized intermediate representation
• Semantic validation: Type, render, and generation validation
• Codegen: Rust source code generation

Build script integration

For build.rs integration (like prost-build or rustemo), use the high-level [compile()] function:

// In your build.rs:
fn main() {
    phenotyper::compile("src/phenotypes/csv.pht", "src/generated")
        .expect("phenotyper compilation failed");
}
