install.sh and install.ps1, copied from the agent-standups source repo, which
stays private. Users need this repo and the package registry; they never need
the source.
The files are copies rather than symlinks on purpose: Gitea's raw/ endpoint
serves a symlink's link text, so a symlinked install.sh would pipe a relative
path into the user's shell instead of a script. sync.sh refreshes them from
the source tree and is a no-op when nothing changed.
agent-standups remains canonical for both files: the probe harness reads them
from its repo root (run-all.sh passes $REPO/install.sh to the R06 probes) and
P8-24 copies them into a scratch tree.
