chore: version packages

Bug 1: Every incoming SSE terminal event reset the 50ms flush timer, not
just cursor-up events. During active Claude runs the timer never fired,
accumulating MBs in flickerFilterBuffer that froze Chrome on flush.
Fix: only reset timer on cursor-up events; add 256KB safety valve.

Bug 2: Shell sessions emit cursor-up on every keystroke for readline
prompt redraws, triggering the flicker filter and delaying feedback.
Fix: skip cursor-up filter for shell mode; disable local echo overlay.

Based on PR #31 by @SGudbrandsson.
