pub fn pro_engine(_ctx: &CliContext) -> Result<Engine>Expand description
Build the unified memstead_base::Engine for a mem-repo-shaped
workspace. Delegates to engine_from_workspace_root which
handles layout detection, mount enumeration, schema resolution,
and readMems hydration in one pass.
Subcommands routed through this helper require mem-repo shape —
they read / write commit-shaped artefacts (workspace dump
snapshots, batch-update commit envelopes) that have no analogue
on a folder-mount-only workspace.
