feat(quota): use official OpenCode Go usage API (#12124)

Migra o quota fetcher do OpenCode Go para a API oficial de uso, com refactor substancial que remove ~1850 linhas de código legado e atualiza a suíte de testes existente inteira para o novo contrato. Validado no worktree combinado (typecheck limpo, testes focados verdes). Obrigado!
