Task H implementer chose code-typescript-v1 but plan + design §3.3 use the
short form (chunker is code-ts-ast-v1 / code-js-ast-v1). Aligning parser
versions to match: rust=code-rust-v1 / python=code-python-v1 / ts=code-ts-v1
/ js=code-js-v1 (Task K). Fixes 2 sites: const PARSER_VERSION + integration
test assertion.
