Coalesced Mountain → Sky emit buffer for sky://command/register.

Extension boot fires 1000+ registerCommand notifications in a tight burst (113 extensions × ~10 commands each). Emitting one Tauri event per command saturated the WKWebView IPC channel that also carries keystroke delivery; users could type for a split second before the burst hit, then nothing. Buffer for one frame (16 ms) and emit a single { commands: [...] } batch instead. SkyBridge’s listener accepts both shapes (single + batch).
