Applies the three suggestions of the review of #375:
- The runner's cleanup keeps one entry per key, whatever its scope: a PR
run that saves under the shared entry's key evicts it for every PR until
the next Monday, and two PRs on the same non-main lockfile evict each
other. Added to the list of cold runs.
- The cache key also hashes the job's CARGO*/RUST*/CC*/CFLAGS*/CXX*/CMAKE*
variables, and ignores the app's own version: changing env: means a cold
run until Monday, a release does not.
- A Monday restore that fails with a 404 after a quiet week is a known
runner race (forgejo/runner#1741), not #234 coming back.

CLAUDE.md and docs/architecture.md still said the Actions cache was
removed until #234 was fixed. They now describe rust-cache, the per-PR
isolation of what a pull_request run saves, the weekly run on main that
writes the shared cache, the expected cold runs, and why check-frontend
has no npm cache. The audit.yml paragraph no longer quotes the outdated
"1 PR in 40" figure.

The runner's cache server is reachable again since the VPS fix of
2026-10-03 (cache proxy pinned to port 28100, ufw rule scoped to the
Docker job networks; diagnosed in #374). Bring caching back to check-rust
through Swatinem/rust-cache, as #232 deferred.
forgejo-runner v12.7.0 keeps what a pull_request run saves private to
that PR, so PR runs alone would only warm later pushes to the same PR. A
weekly scheduled run on main (Mondays 06:30 UTC) and workflow_dispatch
write the shared entries that every PR falls back to.
rust-cache v2.9+ declares node24 and the runner starts JavaScript actions
with the container's node, so the job now installs Node.js 24. zstd is
installed for faster, smaller cache archives.
No npm cache in check-frontend, by decision: with per-PR isolation it
would only serve later pushes of a PR, and npm ci takes 9s there. audit.yml
loses two comments this change makes false.
No CHANGELOG entry: CI configuration only.
