# Wire up Pi config from the workspace bind mount.
#
# Why: ~/.pi holds both config (settings, skills, themes, extensions) AND hot
# runtime state (sessions, logs). We want to persist/commit the config via the
# workspace, but keep sessions on the container's native FS so agent turns
# aren't bottlenecked by virtiofs.
#
# Strategy: keep /root/.pi on native FS, and symlink only the config entries
# out to /workspace/dev_sandbox/.pi/agent/*.
