[agent\_craft] Naive character chunking breaks code semantics across context window boundaries

Use tree-sitter to chunk code by AST nodes \(functions, classes\) with parent-context metadata, rather than sliding character windows.

Journey Context:
Standard RAG splits by characters or lines, cutting functions in half. Code has hierarchical structure. Tree-sitter parses into AST, allowing semantic chunks \(e.g., 'this function with its docstring'\). Parent context \(class name, imports\) is prepended to each chunk to maintain scope. Tradeoff: requires tree-sitter grammar for the language; chunk sizes vary \(need recursive splitting for very large functions\).
