Pull request overview

This PR changes the onlyIssueTypes behavior so that when it’s configured, pull requests are skipped entirely (and without per-PR log output), while issues are still filtered by their allowed issue types.

Changes:

• Added an early guard in IssuesProcessor.processIssues to silently continue on PRs when onlyIssueTypes is set.
• Updated the compiled dist bundle to include the same behavior.
• Expanded only-issue-types tests to cover PR skipping (no log mentions) and to confirm PRs are processed when onlyIssueTypes is unset.
