test(chunk): AST snapshot fixture에 aliases:null 필드 반영

Chunk 구조체에 aliases 필드가 추가된(별칭 인프라) 뒤 chunk-*-ast-v1
snapshot fixture 들이 미갱신 상태로 남아 drift FAIL 이었다. chunk_id·
text·policy_hash·tokenized 는 전부 불변 — 직렬화에 "aliases": null 한
필드만 추가됐다(청크 생성 로직 무변경, 회귀 아님). UPDATE_SNAPSHOTS=1 로
10개 fixture(code c/cpp/go/java/js/kotlin/python/rust/ts + long_section)
재베이크.
