logan 60e10b35a3 fix(bench): reset instance JVM settings for sessions without --jvm
apply_jvm wrote instance.cfg and never restored it, so B5-B12a in run 1
ran on B4's last set (Shenandoah, 6 GB). Within-block verdicts hold
(same JVM on both sides); B7's no-shader baseline is re-run in run 2.

Also: B14 spawn-count automation (b14/: fresh seeded world per run,
offline-located biome sites, datapack entity counts, journaled config
variants) and RESULTS-proxy.md with run-1 verdicts.

"""B14 spawn-tuning measurement (SPAWN-TUNING.md §B14), automated.

One `run` = one client launch into a throwaway world `saves/onionspawn` that holds only
the bench world's level.dat (seed `onionbench`, gamerules, datapack list), so every
chunk around the sites is generated fresh under the config being measured. A generated
datapack sets doMobSpawning true + Creative, parks the player on a barrier block at each
pre-located site (sites.json), and every 60 s prints a parsable chat line
`B14 <sid> <biome> t=<min> biome_ok=1 total=N <entity id>=N ...` counted within 128
blocks. The spawn config variant is journaled through bench.Journal, so `bench.py
restore` undoes a hard-killed run. Stdlib only.
