Analyse Google Ads search terms and suggest negatives

Reads the actual queries people typed before an ad showed, then sorts them into three buckets: converting (at least one conversion), wasted (spend at or above the threshold with no conversions — by default the cost of 10 average clicks in this account, or wasted_threshold in the account currency) and new (not yet added as a keyword or a negative). It also proposes negative keywords with a match type and says why each was chosen. Use when: the user asks where their budget is going, wants negative keyword ideas, or wants to find keywords worth adding. Do not use when: the user means the keywords they bid on rather than the queries that matched them (google_get_keyword_performance). Suggestions are proposals only — nothing is added. To apply them call google_add_negative_keywords, and show the user the list first. Search term data lags roughly a day and Google hides low-volume queries, so the numbers here will not add up exactly to campaign spend. If you are unsure which account, campaign or period the user means, ask them — do not guess ids or dates.
