The matrix spent five runners on work that is almost entirely network
wait: the collection install measured 0% CPU for its whole duration, and
the parent-image pull, the package managers and the push are no
different. One runner carries all five concurrently and frees the other
four.
Losing the matrix loses fail-fast: false with it, so push_all.sh awaits
every build and reports each one by name before exiting non-zero. A
broken distro no longer hides the other four, which is what made today's
triage find three causes instead of one.
Starts are spread by fibonacci seconds because each build opens with a
parent-image pull of several hundred MB. Per-distro logs are grouped in
the job output and uploaded as an artifact, and the pressure report now
carries free -h: memory is the one resource this consolidation contends
for, and an OOM kill would otherwise read as a build error.

Group the shell helpers under scripts/github/ into five subfolders
that match how the workflow files consume them:
runner/ host-runner hygiene (disk, swap, Docker daemon, diagnostics)
cancel/ run cancellation on PR-close and branch-delete events
resolve/ derivation of workflow inputs and outputs from repo state
update/ scheduled Update: Versions pipeline
release/ release-time gates
Drop the now-redundant subfolder prefix from each filename, e.g.
dump_runner_state.sh becomes dump_state.sh and cancel_pull_request_runs.sh
becomes pull_request_runs.sh. Each subfolder carries a README that
describes its scope per documentation.md rules; the top-level README
points at the subfolders without inventorying files.
Propagate the new paths through ten workflow files, three docs
(workflow.md, pipeline.md, secrets.md), and two tests. Fix a real
runtime bug in enlarge_swap.sh, which still referenced the
pre-rename dump_runner_state.sh path. Extend the inline-block-size
lint hint to describe the new subfolder convention.
