Catalog submission workflows post no-op comments to tracking issue

[mnriem]

Problem

The add-community-extension and add-community-preset agentic workflows post no-op comments to the [aw] No-Op Runs tracking issue (#2746) every time they determine an issue isn't a submission for them.

For example, when issue #2744 (an enhancement) was labeled, both workflows ran, correctly determined no action was needed, and then posted comments like:

No action needed: Issue #2744 is not an extension submission (title does not start with [Extension]:, has enhancement label instead of extension-submission label)

These are noise — the workflows are working correctly, but reporting their no-ops clutters the tracking issue.

Fix

Add noop: report-as-issue: false to the safe-outputs frontmatter in both workflow files, as documented in the tracking issue itself:

• .github/workflows/add-community-extension.md
• .github/workflows/add-community-preset.md
