v1.3.0 — o advisor é o graph-eng

O advisor passa a ser o graph-eng. O motor de grafo saiu: no benchmark Minecraft ele levou 5 tentativas, gastou US$ 7,58 e nunca entregou o jogo, enquanto o advisor fechou 55/55 por US$ 1,59.

Changed

• The advisor flow is the only flow. implemente <task> plans (mid model), reviews the plan once (strong model), executes in one continuous session with the strong model as advisor, and only ends done when the supervisor's npm test and npm run build pass. On Claude, steps marked low go to the cheap model by default (--haiku-max low).
• plan <task> now runs the advisor planner and plan review only. It shows each step's complexity and routing, ends with planned, and saves the plan in .graph-runs/advisor-plan.json.
• implemente with no task runs the saved plan, reusing its plan, review and routing. Without a saved plan it blocks with advisor_plan_missing; a plan from another host blocks with advisor_plan_host_mismatch.
• --effort low|medium|max (default medium) is a per-run flag applied to every call. The effort config file is gone.
• The invocation envelope only accepts host and argv.
• READMEs rewritten around the advisor flow, with a short first-steps prompt and the Minecraft benchmark only.

Removed

• The graph engine (bin/graph-run.mjs and its modules), the adaptive triage and its classifier, run memory, the benchmark runner and the old benchmark evidence.
• The clarify, tasks and init commands, and the /grapheng workflow (workflows/graph-eng.js).
• --adaptive and --flow. Passing them, or a removed command, now fails with a message pointing to plan and implemente.
• The local panel (bin/ui-server.mjs, bin/ui/) and its Tailwind dev dependencies.
