lookup.py: exempt code-anchored ASCII identifiers from the mixed
zh/en gate so exact hits are no longer dropped; dedup parent/child
sections in results; validate write-prelude anchors in --check.
references: correct interpreter-verified facts (case-as-expression,
control-flow semicolons, __line__/__stack_frame, tslObjects order,
destroy timing, ErrDefine, truncated outputs), fix headings, scope
qualifiers and reversed quotes; strip dead preamble metadata from all
24 pages.
packaging: exclude __pycache__/*.pyc from playbook and bundle copies;
update build test file-count assertion to match.
