Add keywords to a Google Ads ad group

Adds keywords to one existing ad group, with an optional max CPC per keyword. Keywords that already exist in that ad group with the same match type are skipped rather than duplicated, and the result says which ones were skipped. Use when: the user has agreed on specific keywords, usually after google_research_keywords or google_analyze_search_terms. Do not use when: you would be guessing the terms, or when the campaign only accepts broad match — some newer campaign types reject exact and phrase keywords outright, and Google will refuse the whole batch with a broad-match-only error. If that happens, tell the user rather than retrying with different match types. Write keyword text plainly: no quotation marks for phrase and no square brackets for exact — the match type is a separate field. Bids are decimals in the account currency and are ignored by campaigns using automated bidding. If you are unsure which account, campaign or period the user means, ask them — do not guess ids or dates.
