Non-Serving Keyword Scanner

Finds the keywords nobody knows exist: enabled, eligible, and silent — zero impressions across the whole scan window. Across a large portfolio these accumulate into hundreds of rows of clutter and false coverage ("we're covering that term" — except it never serves). One run scans every account you point it at and produces a single review tab.

One operator owns the workflow end to end: run the scan → triage the tab (rules.md — clusters before rows) → give every row a Pause / Keep / Investigate verdict → route what needs routing. The scanner itself never pauses anything; it is a hygiene instrument, not a savings instrument — every flagged keyword spent $0.00 by definition.
