@agent-native/core@0.57.0

Minor Changes

• 3446e34: Implement AgentChatRuntime factories and AssistantChat runtime mounting for BYO agent chat transports.

Patch Changes

• 3446e34: Hide Pi from the interactive skill instruction picker because the shared .agents target already covers Pi-compatible skills.
• 3446e34: Make plan local check catch every required checklist/question-form field
  the Plan renderer enforces, not just per-item id. Previously a local plan
  missing a checklist item label, or a question title/mode, or an option
  label, passed plan local check with a false green and then got stuck on
  "Loading plan" when the hosted renderer rejected it (expected string). The
  lint now validates id + label on checklist items and options, and id +
  title + a valid mode enum on questions, so authoring mistakes surface
  locally before the browser handoff. The visual-plan/visual-recap skills now
  spell out the full required-field set.
• 3446e34: Accept agent-native plan serve as a compatibility alias for agent-native plan local serve.
• 3446e34: Fix the plan plugin docs to teach the canonical plan local serve command for local-files preview (it previously taught plan local preview, which runs a different local dev-server route), and note the plan serve short alias.
