The 'Set up Docker Buildx' step boots BuildKit, which pulls
moby/buildkit from registry-1.docker.io. A transient Docker Hub
timeout there had no retry (only the build step did), so the whole
build job failed at setup.
Pre-pull the BuildKit image with a 7x/20s retry before the buildx
setup, and pin the action to that exact tag via driver-opts. Once the
image is local, buildx falls back to it if the bootstrap pull fails
('pulling failed, using local image'), so a flaky Docker Hub no longer
breaks setup. Applied to both images-build-ci.yml and
release-version.yml.

Three inline `run:` blocks moved into `scripts/github/runner/`:
* `images_build_outputs.sh "$distros" "$image_tag"` — replaces the
matrix/image_tag computation in the "Compute matrix JSON" step; emits
both outputs to $GITHUB_OUTPUT in one call.
* `distros_matrix.sh "$distros"` — the matrix-JSON primitive
(`split(" ") | map(select(length>0))`), reused by test-dns.yml's
matrix step. Removes the jq duplicate that lived in both workflows.
* The two pre/post-build `Disk pressure` steps now invoke the already-
existing `disk_pressure_report.sh PRE-BUILD` / `POST-BUILD` instead of
duplicating the df/docker-system-df/buildx-du block inline.
Behaviour unchanged; the workflow runs the same commands via the SPOT
helpers.

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.
