test: verify Codecov PR flow

[the0807]

Summary

• Verify the PR → CI → Codecov auto-comment pipeline works end-to-end by adding a single-line comment.
• Change: clarifies the rationale behind the 30s TTL in getRemoteNames.

Expected

• CI (Node 20, 22) passes.
• Codecov posts an automated comment (informational only — should never fail the check).
• Patch coverage: the changed line is a comment, so it likely won't count toward patch coverage; expect a diff-style comment only.

Test plan

• All CI steps pass.
• Codecov comment appears on the PR.
• Project and patch coverage numbers shown in the comment look sane.
