Feature/spinnaker alerts (#527)
* Add .worktrees/ to .gitignore * feat: add Spinnaker alerting rules (12 rules) Add Prometheus alerting rules for Spinnaker built-in exporter covering Orca queue health, circuit breakers, Igor polling monitors, Gate API throttling, Clouddriver errors, and AWS rate limiting. Metric names validated against uneeq-oss/spinnaker-mixin dashboards. * Potential fix for pull request finding Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com> --------- Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com>

This alert factors in the allocation ratio to compute effective capacity.

The threshold of 90% is a rough default. Adjust based on your allocation ratios and workload patterns.

In a healthy Spinnaker, queue_ready_depth should stay at or near 0.
|

Sustained non-zero values indicate Orca cannot keep up with incoming work.
