Struct ModesRenderState 

pub struct ModesRenderState {
    pub map: Arc<HashMap<BufferId, Arc<ActiveModes>>>,
    pub mode_registry: Arc<ModeRegistry>,
}

Active modes per buffer. Slice 3c.final.B.11 — drops the per-frame read_editor(|e| e.active_modes.get(&buf)) call in the modeline is_messages_buffer check to a wait-free Arc-bump lookup off the published snapshot.

Outer Arc<HashMap<...>> for cheap clone-on-publish; per-entry Arc<ActiveModes> so reads don’t clone the inner mode chain. Mutation surface (every activate_mode / deactivate_mode) rebuilds the modified entry’s Arc — rare path (buffer-switch), not per-frame.

Fields

map: Arc<HashMap<BufferId, Arc<ActiveModes>>>

mode_registry: Arc<ModeRegistry>

Read-only after boot — one Arc bump per ModesRenderState publish. Lets the renderer call mode.status_line_items() without an actor round-trip.
