Struct HistoryReader 

pub struct HistoryReader { /* private fields */ }

Scoped read-only handle to a room’s chat history.

Respects DM visibility — a plugin invoked by user X will not see DMs between Y and Z.

Implements HistoryAccess so it can be passed as Box<dyn HistoryAccess> in [CommandContext].
