ci: add anti-slop action

[tarekziade]

What does this PR do?

Activated anti-slop action.

Enabled checks:

• min-account-age: 30 to catch brand-new throwaway accounts, which are common in automated spam waves.
• max-daily-forks: 7 to catch accounts that fork many repositories in a 24-hour window.

This workflow is label-only and does not close or lock PRs. It also keeps max-failures: 2, so a PR is only flagged when both signals fail.

Thanks for the review and pings @ydshieh

I'd also like to hear from @Rocketknight1 , since there were since then more discussion on applying more immediate remedies.

Hey, I'm not certain we want all of this yet! The minimum account age might be good, but the rest are quite difficult to hard filter. In particular, I think the max-comments check will catch e.g. all model addition PRs, and max-description-length is also a bit unreliable. Also, sometimes people have good reason for skipping the PR template, and I'm seeing plenty of agent PRs that keep it, so I don't know if it's a good signal. Can we start with a much smaller list and then iterate over time?

[Rocketknight1]

Also one other thing: The check for the maximum number of repos forked by an account in 24 hours is probably a very good way to catch the worst OpenClaw offenders, and it should catch very few legit accounts - maybe we could try adding that one?

LGTM

Sounds good to me, I'll shrink it
