feat: add web-search and extended-thinking capabilities to the campaign switch AI decider — a per-step web lookup about the contact's company (query derived from contact fields only, results fenced as untrusted, +1 credit charged only when results land, wired through a new tasks SetAISearch) and a thinking toggle that routes to the stronger model tier with a 2048-token budget priced through usage metering, with editor toggles under Capabilities and sequences/ai-credits docs
