Add timing logs to diagnose slow update apply on EDR machines (#947)

[caesay]

The reporter sees a ~14s unlogged gap between the running-process check and the shortcut update phase. The process scan itself completes before the 'Skipping killing self' line is printed, so the stall must be in one of the unmeasured operations that follow: the temp dir deletions or the COM context initialization. Add elapsed-time logging around each so the next field log can pinpoint the culprit.
