Under emulation (or --race with no other name) the race no longer times base alone: emu/test.sh passes again
(9 source checks, the serve protocol with prepare, swap and self-heal, 17 sampled hashes equal to igneum-pow).
Mac table: g256 (256 threads per threadgroup) +17.3% and +21.2% over the shipped 32-thread groups on two
programs, with the live app's worker sharing the GPU; the serve check found the unfair mutex (fixed in 123ee1a).

The engine turns a worker's race line into one TUNING {json} line in the app log (card model as the worker names it,
driver, arch, program class loads and wide loads, every variant's MH/s, winner, gain, the card's power cap and
draw, MH per watt), which the existing intake receives; the card state carries the variant for the dashboard and
one event per race. tools/tuning.mjs aggregates the records from miner_logs per card model (median MH/s or MH per
watt, at least 3 samples, de-duplicated per race) and writes tuning.json; publish-manifest.sh --tuning puts it in
the signed manifest (and now takes --override for consensus.override; both are carried over from the current
manifest when not given, --no-tuning drops it); manifest.rs parses it; ota.rs writes <app data>/tuning.json and
removes it when the manifest drops it; procs::spawn takes an environment and every miner starts with
IGNEUM_TUNING_FILE, which its worker reads at every prepare. Dry run of the publisher against a scratch folder:
tuning and override written, carried over, dropped, signature verified.
docs/plans/miner-perf.md: the signed jobs for PC 1 (fetch the race build of the NVRTC worker, then
relay/playbooks/race-5090.ps1 with the miners stopped: 17 variants, 3 rounds, twice) with the exact publish
commands for the main session; not published by the agent.
