v1.0.5 — named multi-agent borrow + temporary orchestrator

• Borrow every explicitly named agent. When the operator names multiple
  specialists in one request ("웹마스터 카피라이터 불러서 …"), the network router
  now borrows all of them instead of collapsing to the single top-ranked Hub
  candidate. Matching is by the operator's own words against each candidate's
  name, so an off-domain agent the Hub lexically over-ranks no longer wins over
  an agent the operator actually named (_explicitly_named_borrowables).
• Temporary orchestrator for multi-specialist borrows. A request that names
  two or more specialists now returns formation: temporary_orchestrator and a
  directive that puts the executing model in the manager seat — plan the split,
  dispatch each named agent grounded in the project, then synthesize their
  outputs into one deliverable instead of running them in isolation.
• Router fix mirrored into host bundles. Root runtime + Claude Code/Codex
  plugin bundles all carry the same change so packaged hosts do not drift back.
