Slash Commands — Interactive session commands

Provides a /command system for interactive sessions. Commands are dispatched before the LLM — if input starts with /, it’s handled by the command registry instead of being sent to the model.

Built-in Commands

Command	Description
/help	List available commands
/compact	Manually trigger context compaction
/cost	Show token usage and estimated cost
/model	Show or switch the current model
/clear	Clear conversation history
/history	Show conversation turn count and token stats
/tools	List registered tools
/mcp	List connected MCP servers and their tools

    fn execute(&self, _args: &str, _ctx: &CommandContext) -> CommandOutput {
