Engineering: set missing implementation start timestamps

Senior engineers see Building tasks missing start dates, causing inconsistent progress tracking and noisy release reports. Daily checks populate missing start timestamps so engineering gets consistent start times for release reporting.

Overview

Missing start dates create noisy progress tracking and unclear release reports for engineering. This daily check ensures every Building task has a start timestamp, eliminating gaps in release reporting and giving engineering leaders reliable progress signals.
