Check responsive search ad copy against the RSA limits

Checks headlines, descriptions and display paths against the responsive search ad rules before anything is sent to Google: at most 15 headlines of 30 characters, at most 4 descriptions of 90, display paths of 15, at least 3 headlines and 2 descriptions, no duplicates, no shouting in capitals and no repeated or excessive punctuation. Use when: you have drafted ad copy, or the user pasted copy and wants to know whether it will be accepted. Do not use when: the question is about policy topics (medical claims, trademarks) — this tool only checks format and style, not eligibility. Runs entirely inside Adako: no Google call, no cost, no connection required. Fix every error before calling google_create_search_campaign, which applies exactly the same rules and will refuse the whole campaign otherwise. Warnings are advice, not blockers. If you are unsure which account, campaign or period the user means, ask them — do not guess ids or dates.
