Under the hood
Directory-sync turn-end telemetry adds an 'unchanged' outcome and a way to skip reporting
What
The internal function that reports on the directory-sync git worker at the end of a turn now takes a third parameter (defaulting to true) that controls whether the ccr_dir_sync_git_worker_turn_end telemetry event fires at all. Its success branch, which previously matched 'shipped' or 'nothing_to_send', now also matches a new 'unchanged' outcome.
Why
This is internal telemetry refinement for the directory-sync system, distinguishing a turn where nothing changed from one where changes were sent, and allowing that reporting to be turned off when not needed.
