enricobuehler	8265742e74	ci: bust the re-poisoned cargo cache (v3) + burst-guard the runner prune ... This session's push storm refilled the runner to 100% WITHIN the prune timer's 24h window (it only trims >24h), so a build hit ENOSPC and actions/cache saved a truncated target/ -> `error[E0463]: can't find crate for shlex` in ci.yml's clippy. Two fixes: - Bump cargo-target-v2- -> v3- in ci.yml + deb.yml so the poisoned tarball is bypassed (a suffix bump can't — restore-keys falls back to the old prefix; same as the v1->v2 fix). - Harden scripts/ci/docker-prune: run HOURLY (was 6h) with a burst guard — if the disk is still >85% after the normal until=12h trim, prune ALL idle images + build cache (in-use protected). A fast push-burst can fill 99 GB inside any time window, so the disk-pressure trigger, not the age filter, is the real backstop. Applied live on home-runner-1 (reclaimed 95%->66%) and checked in.

enricobuehler	bf65d264fd	ci: bound runner disk + bust the disk-full-corrupted cargo target cache ... The self-hosted runner filled its disk (95%, builds failing on ENOSPC): every CI push builds a sha-<commit>-tagged Docker image per pipeline, and since those tags are never dangling a plain `docker image prune` skips them — they piled up to 589 images / ~85 GB plus 18 GB of build cache. Two parts: - scripts/ci/docker-prune.{service,timer}: a host-level systemd timer (every 6h, Persistent) that prunes images/build-cache/containers older than 24h — in-use images stay protected. Checked in (the runner is hand-provisioned and shared across orgs) and already installed live; reclaimed 89 GB -> 39 GB (95% -> 42%). - ci.yml / deb.yml: bump the `cargo-target-<rustc>-*` cache key to `-v2-`. The disk-full build let actions/cache save a truncated target/ (a dep's .rmeta went missing -> "error[E0463]: can't find crate for pem_rfc7468" while compiling der). A suffix bump is useless here — restore-keys would fall back to the poisoned prefix — so the prefix is versioned to force one clean rebuild. cargo-home is untouched (sources were intact; the failure was a missing build artifact).
