The wasm store gated supertype_symbols / supertype_map_slices /
supertype_map_entries copies on abi_version > LANGUAGE_VERSION_WITH_RESERVED_WORDS,
but every other consumer (language.c, query.c) treats those tables as
present when abi_version >= LANGUAGE_VERSION_WITH_RESERVED_WORDS.
A Wasm grammar built at ABI exactly 15 with supertype_count > 0 ends up
with supertype_count copied into the native TSLanguage but supertype_map_slices
left NULL. ts_query__analyze_patterns then calls ts_language_subtypes,
which dereferences self->supertype_map_slices[supertype] and crashes.

tree-sitter
Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited. Tree-sitter aims to be:
- General enough to parse any programming language
- Fast enough to parse on every keystroke in a text editor
- Robust enough to provide useful results even in the presence of syntax errors
- Dependency-free so that the runtime library (which is written in pure C) can be embedded in any application
