Update type hints in lifecycle hook arguments

When releasing a major version, we will revisit the type hints in lifecycle hooks for more convenience. See https://github.com/openai/openai-agents-python/pull/2915#issuecomment-4265023306 for more context.

This change requries:

• SDK code changes
• Migration guide for existing users (actually no runtime impact; just incompatibility when linting)

Change max_turns default

since 0.16, the max_turns could be None, which means unlimited turns. We'll use this as the default value in v1.

For external contributors, we as core maintainers will handle this. So, please refrain from sending pull requests for this issue.
