fix: remover modelos gerais nao suportados e adicionar vision-model

gustavodiasdev · gustavodiasdev · commit 539388b34023 · 2026-02-10T15:15:20.000-03:00
Modelos qwen3-max, qwen-plus-latest, qwen3-235b-a22b e qwen-flash foram removidos
pois o endpoint portal.qwen.ai nao os suporta (retornava 'model not supported').
O endpoint alternativo chat.qwen.ai/api/v2 nao e viavel pois requer cookies de
sessao do browser e protecao anti-bot.

Modelos confirmados via teste no portal.qwen.ai:
- qwen3-coder-plus (1M contexto, 64K output)
- qwen3-coder-flash (1M contexto, 64K output)
- coder-model (alias auto-roteado para qwen3-coder-plus)
- vision-model (mapeia para qwen3-vl-plus, 128K contexto)

Mudancas:
- Removido provider qwen-chat e arquitetura dual-provider
- Removido endpoint chatBaseUrl (chat.qwen.ai/api/v2)
- Adicionado coder-model como alias de coding
- Adicionado vision-model (qwen3-vl-plus) com suporte a imagem
- Limpeza do client.ts (removido roteamento por endpoint)
- Refatoracao do loader com funcao getValidAccessToken
- Corrigida dependencia circular no package.json
