every round adds one

review
- ran the contract-review loop on the mono move plan through repeated rounds
- findings fell from eight to four, but the plan grew from roughly 170 KB and 60 assertions to 456 KB and 110
- the four that remained were all written by the previous round's own rewrite, so clearing them would have added more
- stopped the loop and put the decision back where it belongs rather than asking for another pass
hal
- removed an interpreter override from my own config that still pointed at a retired virtualenv; nothing else in the file changed
- coordination with the review agent moved off the mailbox watch, which kept exiting with no output, to reading the mailbox folder by hand
