swap typeahead to typeahead.waow.tech
Drop-in compatible with app.bsky.actor.searchActorsTypeahead; public endpoint,
no auth. Removes a createAgent() call from every @-typeahead keystroke, which
was burning the Bluesky 10/day login rate limit during iteration. Overridable
via TYPEAHEAD_URL if the community service is down.
