Deflake perf#32 bound + drop fake ModelAwayState badge

- perf.test.ts: the @200 absolute check flaked under machine load (single-shot vs
  a 1000ms bound; nominal ~230ms). Measure best-of-3 (a micro-benchmark's minimum
  reflects true compute cost, not load spikes) against a 1500ms catastrophic-
  regression guard. The scaling test remains the real O(n²) guard.
- ModelAwayState: remove the hardcoded 'queued: 1 directive' badge (no live queue
  count is wired) and the now-unused Badge import.
