/**
 * Builds a ConnectionUpdate for switching a live session's provider/model
 * connection. Shared by clients (CLI, desktop sidecar, …) so the
 * thinking/reasoning transition rules stay consistent:
 * - `thinking: false` disables reasoning and clears effort/budget.
 * - `thinking: true` (or a provided effort/budget) enables reasoning; an
 *   explicit `thinking: true` resets the reasoning state, so a stale effort or
 *   token budget from the previous connection is cleared unless a replacement
 *   accompanies it. A bare effort/budget without a `thinking` flag updates
 *   only the provided field.
 * - `thinking: undefined` leaves the session's reasoning state untouched.
 * Connection fields are included only when defined; an empty string is passed
 * through (it means "clear"), so callers that want to skip blanks must drop
 * them before calling.
