[us_state_terrorist_orgs] name framework migration

us_state_terrorist_orgs splits one name string into name/former-name/alias with regex and a lookup fallback instead of using the name-cleaning framework (h.review_names / h.apply_reviewed_name_string).

Crawler: datasets/us/state_terrorist_orgs/crawler.py

Ad-hoc logic to retire (~25 lines):

• NORMAL_CASE_RE — crawler.py:6
• split_clean_name returning (name, former, alias) by splitting on parentheses, with lookup fallback — crawler.py:11-35, applied at 49-54

Migration (sanctions crawler — 3 steps):

1. Mirror the existing cleaned names into a suggested h.Names() and call h.review_names(..., default_accepted=True). Output unchanged while reviews accumulate; deploy step 3 ASAP afterwards.
2. Complete the accumulated name reviews for this dataset.
3. Replace the custom logic with h.apply_reviewed_names / h.apply_reviewed_name_string and delete it. Add any custom alias-marker phrases not covered by rigour.names.name_split_phrases_list() as reject_strings under names.schema_rules in us_state_terrorist_orgs.yml.

Migration guide: zavod/docs/extract/names.md (section "Migrating to the name cleaning helpers").

Start with zavod/docs/extract/names.md, then inspect datasets/us/state_terrorist_orgs/crawler.py and us_state_terrorist_orgs.yml. Run the crawler to establish its current output, review the existing name-cleaning helpers, and identify any alias markers needing names.schema_rules reject_strings. Done means the accumulated reviews are complete, output remains unchanged, and the custom name-splitting logic is removed.
