Add tracing #102
We should use structured logging (e.g. with OpenTelemetry) and then scrape the logs to detect failures (e.g. sending a welcome email fails when creating a new member), and then send an alert (e.g. email, IRC) so that a syscom member can take action.
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
