Struct HistoryCommand 

pub struct HistoryCommand;

Show conversation history (spec-068 §13.6).

/history (no argument): the last [session.resume] expand_default_lines messages, sliced before formatting (INV-SP-6). /history N: the last N messages. /history all: pages through the full history in expand_default_lines-sized chunks — never materializes the full history before formatting — with an explicit “may take a moment” notice before the first page. /history next: continues from the pagination cursor left by a prior /history all or /history next.

Output is sent via crate::sink::ChannelSink::send_transcript, not the handle return value, so channels with a structured display buffer (TUI) can backfill per-entry instead of flattening to one string.
