Subject: [PATCH] feat(p10-1d): activate C + C++ in ingest_one_code_asset
 dispatch
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extends 4-arm match (parser_version / chunker_version / extract / chunks)
+ allowlist + tier3_fallback_cv with "c" + "cpp" arms. C uses CAstExtractor
+ CodeCAstV1Chunker; C++ uses CppAstExtractor + CodeCppAstV1Chunker. Both
langs are Tier 3-fallback-eligible (e.g. .h file with C++ syntax may fail
tree-sitter-c parse → Tier 3 paragraph fallback per p10-3 wrapper).
