miner

quantus/miner#2. The measurement gate every kernel and submission change
passes before merge.

crates/bench-harness (lair-owned, never touched by origin merges):
- drives GpuEngine through MinerEngine, one worker thread per card, with
  fixed timed windows after a warm-up; reports per-worker median MH/s and
  spread and refuses (exit 5) when spread exceeds 2%
- captures nvidia-smi state (driver, power limit, draw, clock, temperature)
  before and after, and refuses to run (exit 3) when the enforced power limit
  is not the expected one, since that is the largest confound on these cards
- GPU/CPU parity on random jobs, same shape as engine-gpu's gpu_cpu_parity
  example, exit 4 on any mismatch
- one JSON record per run (schema 1) plus a markdown summary on stdout
- build.rs embeds the commit like miner-cli's

.gitea/workflows/bench.yaml:
- runner containers on the GPU hosts have no device passthrough, so the
  binary is built on cuda-13.0 (Fedora 43, matching the hosts; the rust
  image is Fedora 44 and its binaries need a newer glibc) and executed on
  the host over ssh as gitea_ci
- stops quantus-miner.service for the window and starts it again under a
  trap; refuses to measure a card that is busy with the miner stopped
- benjy (4090, dedicated) by default; host, duration, runs, batch size and
  workers are dispatch inputs; PRs touching engine or service crates trigger
  it and get the summary as a comment
- one measurement per host at a time (concurrency group)

The stop/start sudoers grants were added to lair/quantus infra-setup.sh
(lair/quantus#5) and applied to benjy and quadbrat.

Origin coupling: one line in the workspace members list, marked.
