Tool calls and turn steps dispatched through the plugin event bus

Tool calls and turn steps now flow through the plugin event bus, so plugins can observe a running turn.

What

Tool invocation and turn stepping now go through the same event dispatch that plugins observe, rather than being called in line. This is the plumbing that lets a plugin see and act within a running turn.

Details
  • Each tool call builds an event input, dispatches through core and managed handlers, and does open/close bookkeeping around the call.
  • The interactive session subscribes to turn events and dispatches turn steps, appending their results as messages.
