fix(hkv,rul): add 3 verified hook events; correct globs-rule wording

HKV: add Setup, UserPromptExpansion, PostToolBatch to VALID_EVENTS,
verified live against code.claude.com/docs/en/hooks.md (2026-06-19). A
valid hook using one of these was wrongly flagged "will never fire" — a
user could delete a working hook. Made the "(N total)" hint dynamic so
it can't drift again. Flagged the unverified kebab 'post-session' in a
comment (an existing test depends on it; follow-up check needed).

RUL: reword the globs finding. Only `paths:` is documented; whether CC
ever read `globs` is unverified, so the old "deprecated/legacy" framing
overclaimed (Verifiseringsplikt). New wording steers to the documented
`paths:` field. Updated the coupled fix-engine title match and the
humanizer entry (which also carried the "field was renamed" overclaim).

Suite 950 -> 954 (badge bumped). self-audit A/A, scanner count 13. No
version bump — these land in the pending v5.4.1 patch.
