TL;DR

This PR is an automated release for version 0.22.0, introducing new features such as async_timeout_seconds for invocations, browser pool enhancements, and improved agent authentication, alongside a refactor to remove browser persistence UI.

Why we made these changes

This is an automated release to publish new features, enhancements, and refactors to the kernel-go-sdk.

What changed?

• Features:
  • Added AsyncTimeoutSeconds to InvocationNewParams for specifying asynchronous invocation timeouts (10-3600 seconds).
  • Polished browser pools.
  • Enhanced agent authentication with optional login page URL and auth chain.
• Refactors:
  • Removed persistence option UI from the browser module.
• Release-related updates:
  • Updated .release-please-manifest.json, .stats.yml, CHANGELOG.md, README.md, and internal/version.go to reflect the 0.22.0 release.

Validation

• TestInvocationNewWithOptionalParams in invocation_test.go was updated to include AsyncTimeoutSeconds with a value of 600 seconds.

Performed full review of beb387c...41e8d6a

Analysis

1. Validation Gap: The documented constraints for AsyncTimeoutSeconds (10-3600 seconds range) exist only in comments with no client-side validation, forcing reliance on server-side validation and potential wasted round-trips.

2. Missing Relationship Validation: The code doesn't enforce the relationship between AsyncTimeoutSeconds and the Async flag, allowing users to set a timeout value without enabling async mode.

3. Limited Test Coverage: Tests appear to cover only the happy path scenarios, potentially missing edge cases around validation and parameter relationships.
