Rediseño tool results + compactación por step + integración Docker

- Tool results completos en conversación (como Claude Code/Cursor)
  en vez de resúmenes en system prompt
- Parser multi-tool: trackea tool calls por tool_call_id para
  OpenAI streaming interleaved
- Deduplicación por fingerprint + detección de loop cuando todos
  los calls de un step son duplicados
- Compactación inteligente por step: el orquestador decide cuándo
  comprimir steps anteriores (cambio de agente o >3 steps)
- stdio.js lee URLs del .acai como fallback (local_web_url, local_forge_host)
- Buffer MCP aumentado a 1MB para respuestas grandes
- Dockerfile adaptado para build context desde raíz del proyecto
