Erik JohnstonandClaude Opus 5.5 8ae4e7d6b1 Add a Postgres proxy that counts round trips, and use it in the bench ...

`scripts-dev/pg_roundtrip_proxy.py` sits between Synapse and Postgres. It
counts round trips, a client message after a server message on the same
connection, can add latency to each, and records the protocol messages
and SQL of each round trip. SIGUSR2 resets it and SIGUSR1 writes the
counts and log to a file.

`createroom_bench.py --proxy-delay-ms N` runs the server through it and
reports the round trips per request beside the timings. With a delay,
the extra wall time over a run without one shows how many of those round
trips the request waits for in turn. A new `e2ee_invite` scenario is the
room the E2EE monitor creates on jki.re, and `--scenarios` picks a
subset. `persist_bench.Server` honours `PGPORT`.
