List error issue groups sorted by frequency.
Groups errors by FingerprintHash and shows the count, exception type,
message, status, and last seen time for each group. This is the starting
point for debugging production errors. Use --since to control the time
range and -s to filter by service.
After finding an issue, copy its fingerprint hash and run
strada issues view <fingerprint> to see the full stack trace and
recent events.
By default only 'open' issues are shown. Use --status to filter by
triage state: open, resolved, muted, ignored, or all.
