Suggesting path-cleaning rules

Many teams never configure path cleaning, so their Web analytics breakdowns fragment across thousands of near-identical URLs. This feature proactively suggests cleaning rules for the web-analytics precompute cohort: weekly, for each team, it samples real paths, asks the LLM for {regex, alias} rules, validates them against the team's own paths, and stores them for review.

It only suggests — it never auto-applies. Applying rewrites historical numbers in every cleaned chart, so that stays a human decision (the existing settings UI, or the --apply flag below after review). To hand-author or directly apply rules, use the managing-path-cleaning-rules skill.
