Function resolve_option_in 

pub fn resolve_option_in(
    registered: &[(AdapterRecord, Manifest)],
    adapters_dir: &Path,
    option: &str,
) -> Result<Manifest, RegistryError>

Resolve an adapter option against an already-loaded registered set — the daemon seam. registered() is called once per edge event, then every hosted shell is re-resolved against the in-memory slice rather than reloading each parent from disk. Same contract as resolve_option (split → parent lookup → overlay), but the parent comes from the slice; local overlays still read from adapters_dir. Returns the merged, validated manifest (the record already lives in the slice).
