codetether-agent 4.6.0

//! `/ask` — ephemeral side question handler.
//!
//! Runs a single, tool-less completion against the session's current
//! provider using the full conversation as context, renders the answer
//! as an in-chat system message, and **never mutates session history**.
//! Mirrors Claude Code's `/btw`: full context, no tools, single reply,
//! ephemeral. Works across every provider in the registry.

/// # Arguments
///
/// * `app` — TUI state; receives the answer + status updates.
/// * `session` — current conversation; **read-only**, never mutated.
/// * `registry` — provider registry. [`None`] ⇒ status-only error.
/// * `question` — trimmed text after `/ask`. Empty ⇒ usage hint.
///
/// # Errors
///
/// Provider errors are surfaced via `app.state.status`; this function
/// does not return a `Result`.
