fix issue where autopilot was continuing even though it was basically done

[Copilot]

Pull request overview

This PR adjusts the Copilot extension’s tool-calling autopilot loop to stop continuing when the model appears “done” (i.e., returns no tool calls), and updates the user-facing autopilot progress wording accordingly.

Changes:

• Update shouldAutopilotContinue to stop nudging when the model returns a text-only response with no tool calls, and to stop after a prior nudge produced no tool calls.
• Refine autopilot progress messages (tool-call-limit extension, error recovery, and “task not complete” continuation).
• Extend the autopilot unit tests to cover the new stopping behaviors and update test helpers to support text responses.
