• Closes Remind issue assignees about missing backport PRs #91.
• Checks hourly, like auto-bump and expiration tasks, for issues closed as completed for at least 24 hours, with a related PR merged into main.
• Uses backport/<version> labels to require open or merged PRs targeting release/<version>, linked in Development.
• Automatically links matching backport PRs when opened, edited, or reopened, using closing keywords such as Closes #123, without waiting for the hourly check.
• Mentions current assignees about missing backports and repeats reminders daily, preserving history across restarts.
• Skips archived release branches, backport/main, reopened or locked issues, and closures other than completed.
• Added by Codex

We have quite a lot of backports to manage, and it's PITA to notify assignees to provide backports if forget.

@stianst WDYT?

Talked with @stianst and decided that we don't remind assignees to provide backports for now. We can revisit later, if we have more struggles with it.

We agreed to at least link the PRs to the Deployment section:

• Automatically link backport PRs to issues in Development #95
