Frozen contract: single PR with code-c-ast-v1 + code-cpp-ast-v1. C symbol
= function name only (no nesting). C++ symbol = namespace::Class::method
(recursion). .h → C (design §3.5); C++ headers' parse failure picked up
by p10-3 Tier 3 fallback. tree-sitter-c + tree-sitter-cpp workspace deps,
version bump 0.15.0 → 0.16.0.
