vegeta reads a leading 0 in its worker count as octal, so 00 gave no
workers and 010 gave eight. The clients check before the build now
refuses any value starting with 0, zero included. The duration needs no
change: vegeta reads it as decimal, so 05s is five seconds.
TODO.md: the load test entry is once, at the top of Completed Steps,
and the entries for #206 and
#204 are no longer repeated.
Model: opus-5-5
A duration must be a whole number above zero followed by ms, s, m or
h; anything else prints the usage line and exits 2 before the image
build, as a bad number of clients already did. vegeta takes 0 to mean
no end. The load test's entry moves to the top of Completed Steps in
TODO.md.

script/loadtest [duration [clients]], or make loadtest, is a benchmark
that script/check does not run. It builds the image and vegeta from a
pinned commit, then for each scenario starts a new pixad container and
a new cmd/loadtest-origin container, an upstream host that answers every
path with one generated JPEG: a cached image (hit), a new source image
per request (miss), and each new source image asked for by all clients
at once (herd). It prints vegeta's report, pixad's peak resident memory
and the requests the origin got. The containers share a network in
203.0.113.0/24, as pixad refuses private and local upstream addresses.
README.md says how to run and read it; TODO.md records a small baseline.
