// Lets non-React callers (hover-bar's click rule, Agent's chat submit)
// trigger the QE canvas's save. Without this, every implicit-close gesture
// — cross-block click, click-outside, Ask AI pill, agent chat submit —
// silently discards the user's in-flight edits.
//
// BlockTextEditor registers its `handleSave` on mount. The bridge stays a
// no-op when nothing is registered (no QE canvas open) so callers can
// fire-and-forget.
//
// Cross-block click passes `alsoClear: false` so handleSave skips its
// final `clearSelected()` — the new click is already calling
// `setSelected(B)` synchronously after, and we don't want the async save
// completion to overwrite B with null.
