The new setting image_requests_per_minute (PIXA_IMAGE_REQUESTS_PER_MINUTE),
default 600, caps the GET and HEAD requests one client sends to /v1/image/
and /v1/e/ per minute; the next is answered 429 with Retry-After and the
image routes' JSON error body. It uses the login limit's RateLimit
middleware, so clients are told apart the same way, behind the CORS
middleware, so a preflight is not counted. 0 turns it off, as
script/loadtest does; a negative or non-integer value stops startup.
TestEnvironmentSetsEveryKey gains the new variable, under the standing
approval in #64. To stay within the
linters' limits, the sentry_dsn check moves unchanged into
validateSentryDSN, and the cache_max_bytes explicit flag is set in one
line.

script/loadtest [duration [clients]] (make loadtest, defaults 10s and 4)
measures pixad in three scenarios: hit (one cached image), miss (a new
source image every request) and herd (each new source image asked for
by all clients at once). For each it prints vegeta's report (requests
per second, p50/p95/p99 latency, status codes), pixad's peak resident
memory and how many requests reached the origin. It is a benchmark, not
run by script/check. The origin it uses, internal/loadtestorigin behind
cmd/loadtest-origin, answers every path with one generated JPEG. Bad
arguments are refused before the build. README.md says how to run and
read it and keeps 1-5k r/s as a target not yet measured at scale.
