Subject: [PATCH] fix(models): hide unsupported Gemini Live discovery (#11710)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Obrigado! Validado em lote combinado (8 PRs, release/v3.8.51):

- Follow-up correto de #10590/#10591 — omite modelos Gemini Live-only da descoberta dinâmica, preserva chat para modelos híbridos.
- Teste focado atualizado: `tests/unit/gemini-models-parser.test.ts` — 6/6 verde.
- Gates estáticos do lote OK (typecheck, lint sem regressão, complexity, cognitive, file-size, changelog-integrity).
