Value Source Picker
One picker for every action-engine slot that accepts literal-or-reference. Wire format matches the action engine's resolver byte-for-byte. Used in declarative action editors — Edit values, Create field maps, function args, config-query filters. Mode set narrows per consumer via `allowed`.
