v0.6.0

Changed

• Show the bare thinking effort level in the model segment (K3 max instead
  of K3 thinking:max) in every layout; boolean thinking keeps the
  thinking label.
• While the goal badge is up, the speed segment shows throughput only: the
  gen timer, TTFT and the compaction state all hide (the badge already
  carries the session clock), freeing space for the badge.

Removed

• Drop the full layout tier together with its exclusive Context segment,
  version suffix, and Cache token counts. Layouts are now compact and normal,
  and the width defense degrades normal -> compact; read the host-drawn
  line 2 for context usage.

Fixed

• Count only agents with a fresh speed reading in the fleet throughput
  figure: an agent still waiting on its first step stays in the gen-ticker
  head count but no longer inflates the N agents @avg parenthetical, so
  the displayed total, head count and average stay consistent.
