Erik JohnstonandClaude Opus 5.5 c7bec795fb Add a benchmark of event persistence at each Rust level

`scripts-dev/persist_bench.py` starts a real Synapse process per
`rust_event_persistence` level, on a fresh Postgres database with the
native driver, and runs the same workloads through the client API:
concurrent messages, membership churn, joins into a room with many
state events, and a redaction storm. For each, it reports wall time,
the CPU of the reactor thread and of the process, the change in
resident memory, and the `persist_events` transactions from the metrics
endpoint.

On this sandbox, 20 users, two runs of each level:

    workload         level        ms/event   txn ms   proc CPU s
    messages         off             19.7     56.7       29.1
    messages         full            14.4      4.2       23.6
    membership       off             49.6      7.4        9.5
    membership       full            41.3      4.4        8.0
    big_state_joins  off             58.1      7.7        1.05
    big_state_joins  full            50.5      4.7        0.93
    redactions       off             13.1     38.5        3.2
    redactions       full            11.5      7.1        3.2
