2db6ff4f63 Support separate output node types in extractor generator 
Language and LanguageSpec gain optional output_node_types field.
When set, the generator produces dbscheme/QL from the output types
and the extractor validates TRAP against them.

All existing extractors pass None (no behavior change).
Ruby extract() calls gain vec![] for the new rules parameter.

34e4144a14 Integrate yeast with shared tree-sitter extractor 
extract() gains a rules parameter. When empty, uses tree-sitter native
traversal (no behavior change). When non-empty, runs yeast desugaring
and extracts via traverse_yeast.

Adds AstNode trait abstracting over tree_sitter::Node and yeast::Node,
with minimal changes to existing Visitor methods (Node -> &N in 6
signatures). Falls back to un-desugared AST on error.

ed60f05f2e Add AST dumper for human-readable tree output 
Produces indented text showing node kinds, named fields, and leaf
content. Unnamed tokens are hidden unless inside a named field.
Used by tests for readable assertions.

e6026a4cba Add YAML node-types format and converter 
Human-friendly YAML alternative to tree-sitter node-types.json with
three sections: supertypes, named, unnamed. Supports bidirectional
conversion and building Schema objects from YAML.

Includes CLI binary (node_types_yaml) and documentation.

3b20424bbc Add yeast test suite 
12 tests covering parsing, queries, tree building, desugaring rules,
cursor navigation, and the shorthand rule! syntax.

Tests use a custom output node-types.yml with named fields for all
children (parameter, stmt, index), loaded via schema_from_yaml_with_language.

356fd97b4e Add yeast crate: AST desugaring framework with proc-macro DSL 
YEAST (Yet another Elaborator for Abstract Syntax Trees) is a framework
for transforming tree-sitter parse trees before CodeQL extraction.

Core components:
- shared/yeast/ — Ast, Node, Schema, query matching engine, captures,
  FreshScope, BuildCtx
- shared/yeast-macros/ — proc macros: query!, tree!, trees!, rule!

The query language is inspired by tree-sitter queries:
  (assignment left: (_) @lhs right: (_) @rhs)

Templates support embedded Rust ({expr}), splicing ({..expr}),
computed literals (#{expr}), fresh identifiers ($name), and captures (@name).

The rule! macro combines query and transform:
  rule!((for pattern: (_) @pat ...) => (call receiver: {val} ...))
