What was changed

• 💥 BREAKING CHANGE - by default, now all __contains__ and __getitem__ accesses to in-sandbox sys.modules for modules that are not there, but they are in outside-sandbox sys.modules and are configured pass through, are lazily added to in-sandbox sys.modules and returned
  • This fixes a longstanding issue where transitive passed through imports were not in sys.modules inside of sandbox
  • This was affecting Pydantic because they use module namespace contents in sys.modules to affect how they evaluate type hints without importing
  • This is technically a backwards incompatible change because it affects sys.module behavior inside of sandbox, so we have provided a disable_lazy_sys_module_passthrough option in sandbox restriction config to opt-out if it breaks user workflows
• Update openai-agents to >0.1
• Set the OpenAI data converter as the Pydantic converter
  • The sys.modules issue being solved alongside an upstream resolution in OpenAI agents means that native Pydantic data converter can be used
  • Use of the OpenAI data converter is deprecated (and will be removed when we move to plugins)
• Default all agents and openai modules (and their children) as passthrough for the entire SDK
  • We can consider instead making this part of the plugin when that comes around instead of global
  • Updated code to remove the manual passthroughs
