r"""
Load this PC's older Run events into `dbo.CV_RunEvent` (2026-10-30), once,
so the Portal on Dokploy lists the Runs from before the bot copied its
events to the database itself. A Run already in the table is skipped, so a
second run of this tool adds nothing.

    python tools\import_run_events.py            # import
    python tools\import_run_events.py --dry-run  # only say what it would do

Run it from PowerShell on the bot PC (Windows login to the database).
