Forgejo 15 has no REST endpoint to download an Actions artifact — the
only path is the web UI download route, which is keyed by the run's
global id rather than the per-repo run number shown in run-page URLs.
The REST artifacts list route keys off the run number instead, so the
two can't be chained directly.
artifact-get takes the run number (what pr-status surfaces as a CI
context target_url), translates it to the global run id via the REST
runs list by matching each run's html_url tail, then GETs the web
download route with the agent's forge token. Saves the artifact zip to
a path (default /tmp/forge-artifact-<name>.zip) or streams to stdout
with -o -.
The artifact name is percent-encoded into the path. The encoder that
list already used for query-string filters is promoted to a shared
verbs::pct_encode helper so both call sites stay in sync.
Lets an agent pull a CI-built artifact (e.g. a paper PDF) into /shared
without host access.
