actions/cache@v4 is a Node action fetched from github.com - unreachable from the runner network, and job containers are deliberately nodeless. scripts/ci-cache.sh speaks the act-runner artifactcache REST protocol directly (lookup, reserve, upload, commit), verified against the forgejo-runner source (act/artifactcache/handler.go).

• Keyed on the poetry.lock hash, per python version (tests) + docs/build jobs
• Caches the poetry venv + ~/.cache/pypoetry + ~/.cache/pip
• Best-effort: any cache failure exits 0 - CI never breaks because of the cache
• First run: save-only (miss); this PR run itself validates both paths

Measured context: jobs spend a chunk of their 110-175s in poetry install; warm-cache runs should cut that on repeat commits.

CI: cross-job dependency caching via act-runner cache server (shell client) ... 0d0f043c14

actions/cache@v4 is a Node action fetched from github.com — unreachable
from the runner network and the job containers are deliberately nodeless.
scripts/ci-cache.sh speaks the act-runner artifactcache REST protocol
directly (lookup/reserve/upload/commit), keyed on poetry.lock hash, and is
best-effort: cache failures never fail a job.

Caches the poetry venv + pip/pypoetry caches for tests (per python
version), docs and build jobs.
