On the self-hosted-fast runners /proc/meminfo isn't readable, so awk exited 2 and failed every
job the sizing step runs in (Doc tests on #2509 and #2510, on minisforum-fast-2 and -3) before
compiling anything. Sizing is an optimisation: without a readable memory figure (meminfo or a
numeric cgroup limit) the script now sets nothing and Cargo keeps its default. Also drops
`set -e`, so no other probe can fail the job.

Build tests on the untrusted runners (fork PRs, gVisor on shared boxes) fail intermittently with
rustc killed mid-crate ("exit status: 2", no diagnostic) on the biggest crates: solidcraft-engine,
ui-egui. Nothing limits Cargo's parallelism, so it starts one rustc per core the sandbox reports.
scripts/ci/build-jobs.sh sets CARGO_BUILD_JOBS from the memory available (and the cgroup limit,
where lower) at 3 GB per job, capped at nproc, and logs the numbers it saw.

Clippy, the doc tests and test shards 1-2 of pushes to main and merge-queue
groups run on the self-hosted runner, alongside GitHub's runners for
everything else. Pull requests, the nightly run and Run workflow stay on
GitHub's runners. Clippy and the doc tests keep warm build directories
outside the checkout (scripts/ci/warm-target.sh).
The test archive is still built on GitHub's runners: the self-hosted
machine has a newer glibc, so binaries built there don't start on
ubuntu-24.04.

Clippy, the test archive and the test shards cover the packages a PR changes plus their dependents. Main, nightly and manual runs stay full.
