//! Shared channel-session resolution: look up by stable suffix, fall back to
//! legacy exact-title rows with forward-migration, archive on idle, otherwise
//! create.
//!
//! Issue #121: title-based session lookup orphans rows once the agent's
//! auto-rename rewrites the title. Discord, Slack, and WhatsApp all used
//! `find_session_by_title(&exact_template)`, so after a rename the next
//! message's lookup missed and a duplicate session was created on every turn.
//!
//! Fix mirrors the Telegram approach (PR #123): embed a stable `[chat:<id>]`
//! suffix at session creation, look up by suffix on subsequent messages, and
//! one-shot migrate any legacy pre-suffix row when found.
//!
//! Telegram has its own resolver in `channels::telegram::session_resolve`
//! because it also juggles an in-memory chat→session binding map and group
//! label-refresh policy. Discord/Slack/WhatsApp don't need either of those.
