"""
Rewrite the "Violence Used" line of every reviewed summary in summary-overrides.json so
that it names DETENTION explicitly where the victim was held, and says "No detention"
where the summary already states the attack was foiled, a snatch, or a hit-and-run.

Rule: README-START-HERE.md, "Definitions". Nothing is added that the summary does not
already say: a line gets the "Detention —" label only when that same summary (any
category) already describes the victim being held, tied, handcuffed, locked in, taken
away or abducted; the supporting phrase is checked before the edit. Idempotent.

Supersedes the Violence Used wording in build_overrides_batch1..7.py; summary-overrides.json
is the authoritative store. Run build_cases.py --all and verify_all.py afterwards.
