Description

I'm starting to do some work with Monitor, and one of the things i realized I was going to want is an easy way to detect Queries that result in `ANYTOKEN` style QueryIndex documents – requiring a "forward search" test against every future `match(Document)` call.

The simplest solution I could come up with is a Presearcher "wrapper" – something that might be generally useful for other users – but I'm certainly open to other approaches.

Research direction

Start by reading Monitor's Presearcher flow and the future match(Document) calls described in the issue, then compare the proposed wrapper with the attached LUCENE-10570.patch. Done means Monitor can reject registration of queries that produce ANYTOKEN-style QueryIndex documents without requiring a forward-search check for every match(Document) call.
