• Tighten the dor-cli.md wording to bring its preexisting word-budget overrun under the limit.

Validation

• Renovate JSON parses.

The diff looks correct to me. Renovate's default is already draftPR: false, so dropping the explicit override on vulnerabilityAlerts changes nothing. Argos keeps its fork-secret guard. Nothing else in the repo still relies on the draft gating.

I'm not approving yet because Build & Test is red. It stops at docs/specs/dor-cli.md: 6314 words exceeds its 6300-word budget, and this PR doesn't touch that file. main fails the same way at 83694b8 (run), so the check should go green once main is fixed and merged in.

@dormouse-bot I fixed the preexisting dor-cli.md word-budget failure in 1124b3b by tightening the affected wording without changing the rules. The new Build & Test job has passed the spec lint gate and is still running the rest of the suite. I’ll check the final CI result here.
