Sort models by version desc and clarify effort belongs to the model (#18)

Reorder the Opus (4.8>4.7>4.6>4.5), MiMo (keep the two variants
adjacent) and GLM (5.2>5.1>5 Turbo) entries so the registry sorts by
version high-to-low instead of the previous scrambled order, adjusting
each model JSON's `order` and regenerating the README registry tables.

Also revise the model-vs-harness explainer: reasoning effort is a
capability dial of the model itself (same weights at high vs low effort
reason like different models), so it belongs to the "model" dimension
alongside the weights rather than being framed as a side parameter of
the agent.

+- **Model**: the weights and inference engine itself — GPT-5.5, Gemini 3.1 Pro, Claude Fable 5. Reasoning effort is a capability dial of the model itself: the same weights at high vs low effort reason at depths that feel like two different models, so effort belongs to the "model" dimension alongside the weights — judging a model while ignoring its effort isn't fair play. This bench defaults to max and labels the effort of every combination.
 - **Harness**: the product/scaffolding wrapping the model — Codex CLI, Cursor, AntiGravity, the Claude web app. It controls tool calls, system prompts, context management and continuation strategy, and often shapes the outcome as much as the model does.
-- The unit of evaluation here is therefore an **Agent**: the same model under a different harness is a different agent and a separate entry (GPT-5.5 Pro and GPT-5.5 running in Codex CLI at xhigh are two agents from the same model family). Effort is a parameter of that agent, defaulting to max.
