📝 Summary

Summary by CodeRabbit

• New Features
  • Added scheduled automatic retesting at regular intervals.
  • Added support for manually triggering a retest.
  • Updated retest requests to use the /konflux-retest command.

Walkthrough

The Konflux auto-retest workflow now runs every ten minutes at scheduled offsets and supports manual dispatch. It calls a periodic reusable workflow with read permissions and uses /konflux-retest instead of a check-name suffix.

Changes

It updates the reusable workflow reference, adds read permissions, renames the job to retest, and passes retest_command: '/konflux-retest'.
