## Human Summary
OpenAI Agents SDK Python v0.22.3 fixes bugs across core tool approvals, resume handling, Windows sandbox paths, session concurrency, and extensions, along with dependency security updates.

## Agent Summary
OpenAI Agents SDK Python v0.22.3 addresses several stability issues: conditional approvals now use validated tool arguments, tool-not-found outputs are delivered on server-managed resume, sandbox command paths stay POSIX on Windows, async SQLite handles concurrent startups, and subprocesses are reaped on early stream closures.

## Body
OpenAI Agents SDK Python v0.22.3 brings several bug fixes and dependency updates without breaking changes. Key core fixes include aligning conditional approvals with validated tool arguments and ensuring tool-not-found outputs are properly returned during server-managed resumes. For platform compatibility and runtime safety, sandbox command paths are maintained in POSIX format on Windows hosts, and subprocesses are now properly reaped upon early stream termination. Session handling has been improved with fixes for concurrent async SQLite initialization, correct pagination handling without misusing session limits as page size, and ID preservation in AdvancedSQLiteSession delete operations. Dependency updates address known vulnerabilities without modifying SDK APIs.

## Recommended actions
- Upgrade to openai-agents v0.22.3 to receive concurrency, subprocess cleanup, and core approval fixes.
- Verify Windows sandbox executions and SQLite session concurrency behaviors after upgrading.
