* Parses the configured usernames into a normalized, deduplicated handle list. * * Handles are lowercased and stripped of a leading `@` before deduplication so * that `jack`, `@jack`, and `Jack` collapse to a single entry — avoiding a * duplicate user-id lookup and a redundant `userIndex` slot i

(value: unknown)

 * cursor's `userIndex` stays aligned to the same array across pages.
