Two new steps wrapped around the existing push/create flow:
1. Dedupe before push: hash the local diff vs origin/<base-branch> and
compare against gh pr diff of every open PR (any author, any branch)
targeting the same base. On a match, exit 0 without pushing and
without creating a PR. This is what stops the same image-version
bump from being opened repeatedly.
2. Supersede after create: close every other open PR whose branch
starts with UPDATE_BRANCH_PREFIX with a "Superseded by #N." comment.
The prefix filter keeps the bot from ever closing repository-refs,
skills, or human-authored PRs, even though dedupe itself sees them.
CRLF normalization on both sides of the hash compare so a runner that
checks out the patch with native-CRLF translation still produces a
stable hash.

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.
