How to use CDEDUP: collapse near-duplicate answers

CDEDUP finds entries that mean the same thing and collapses them, reporting clusters and memory reclaimed — best run as off-peak maintenance.

A semantic cache fills with rewordings of the same answer. CDEDUP merges them to reclaim memory. It's heavy on a loaded instance, so schedule it off-peak.

> CDEDUP
1) "clusters merged: 38"
2) "entries removed: 112"
3) "memory reclaimed: 4.1 MB"

Because it runs on the single-writer actor, a large pass can block live traffic — run it on a cron, not in a hot loop.
