fix(mcp): drop unused runner.abort + recorder.reset hacks

The pause-and-abortRun chain alone is enough: resolveContinue releases
the current pauseSession, abortRun causes the next pauseNow-queued
pauseSession to reject inside setPauseHandler, the rejection propagates
through the recorder to codecept.run, and Mocha's runningNow clears
naturally. Reaching into mocha._runner / _previousRunner / .runner and
calling recorder.reset() were speculative — the timeout repro still
clears Mocha state without them.
