v0.3.24

Added

• Model-specific thinking block shapes (ADR-0017) — ThinkingConfig widened
  from {type:"adaptive"} to a discriminated union supporting
  {type:"enabled", keep:"all", budget_tokens} (Kimi Preserved Thinking) and
  {type:"enabled", clear_thinking:boolean, budget_tokens} (Z.ai Preserved
  Thinking). On the Anthropic/Claude-Code stamp path, umans-glm* models now
  force thinking to {type:"enabled", clear_thinking:false, budget_tokens:32000}
  and umans-kimi*/umans-coder models force to
  {type:"enabled", keep:"all", budget_tokens:32000}. Other families (flash,
  qwen, fallback) keep {type:"adaptive"}. Disabled thinking blocks stay
  respected per policy.canDisableThinking. Per-family shapes are data-driven
  via StampPolicy.thinkingShape, not if-branches.
