Module grammar 

Core structures and parsing logic for Tree-sitter grammars.

This module defines how Sapling understands and manipulates the declarative shape of a language: the grammar itself. Everything else in the compiler builds upon these types. Core structures and parsing logic for Tree-sitter grammars.

This module defines the internal representation of a grammar as parsed from Tree-sitter’s JSON format. It uses facet_json for deserialization and provides ergonomic accessors for inspecting rule properties and structure.
