4//! `/conv` slash command handler — browse durable conversation-sessions (spec-068, #5343).
5//!
6//! Channel-agnostic by construction (the `CommandHandler`/`ChannelSink` pattern): works
7//! identically whether typed in the CLI, TUI, or Telegram, mirroring `zeph serve-sessions`'s
8//! `GET /sessions`/`GET /sessions/:id` REST endpoints but reading through
9//! [`crate::SessionControlAccess::handle_conv`] instead of HTTP.

20/// Syntax: `/conv` or `/conv list` — list sessions; `/conv show <id>` — one session's metadata;
21/// `/conv resume <id>` — live-swap this conversation onto an existing session, replaying its
22/// durable log; `/conv fork <id>` — eager-copy `id` into a fresh session and swap onto it
23/// (spec-068 §9, D-9).
