The event loop now time-boxes `recv` while an indicator recompute is owed: every keystroke hides the indicator and arms an `INDICATOR_DEBOUNCE` (1s) window; once typing pauses that long the runtime computes `App::input_validity_verdict` and shows `[ERR]` / `[WRN]`. An idle session (nothing owed) still blocks plainly on `recv` — no wake-ups. `update()` stays pure — the debounce timer lives in the runtime; `App` only holds the resulting `input_indicator` state, which the runtime clears on a keystroke and sets when the quiet interval elapses. `App::input_validity_verdict` is tested directly (a simple-mode verdict, and silence in advanced mode / the `:` one-shot); the debounce timing itself is runtime-loop glue, covered at the integration level.
