Crate husk_codegen_js 

Minimal JavaScript AST and pretty-printer for Husk codegen.

This crate currently defines:

• A small JS AST (expressions, statements, modules).
• A pretty-printer that renders the AST to a JS source string.
• A minimal lowering from Husk AST to this JS AST for simple functions.
• Source map generation for debugging.
