Written for the other machine, which asked. Everything in it was read off the
running host rather than remembered.
Also adds docker/ci/ -- the CI image recipe and a capped runner -- because the
image existed on exactly one host and its Dockerfile was in a scratch directory
under /tmp, which was swept. That is the same shape as every other thing this
consolidation has turned up: something correct that exists in one place.
docker/ci/Dockerfile rust 1.98.1 + the apt list copied from ci.yml
docker/ci/Dockerfile.ffmpeg + ffmpeg, which sylpheed-export shells out to
docker/ci/run 6 CPUs / 7 GB / NO SWAP, named cargo volumes
The rule the runner exists to enforce: every heavy command goes in the capped
container. CARGO_BUILD_JOBS caps codegen units, not rustc's threads, not the
linker, not the test harness -- a bare host build is unbounded and has frozen
this box repeatedly.
The document also records the two agent defects the other machine will meet:
a brief change does not reach a RESUMED session, and nothing brought an agent
back to its own red PR (fixed in #24, which is itself subject to the first).
