Prefer direct tools in live agent code guidance

[Ker102]

Summary

• update the current LangGraph agent's execute_code tool description so Python is an escape hatch, not the default path
• point the agent toward direct MCP tools for mesh, material, lighting, camera, render settings, UV, and export operations
• add a regression test that blocks reintroducing broad execute_code-first wording

Validation

• npx tsx scripts/test/test-live-agent-execute-code-guidance.ts
• npx tsx scripts/test/test-direct-tool-surface-coverage.ts
• npx tsx scripts/test/test-direct-tool-planning-prompt.ts
• npx tsc --noEmit --incremental false
• npm run lint
