Code Review

This pull request updates the @a2a-js/sdk dependency to version 0.3.11 in both packages/core and packages/a2a-server. The changes are straightforward, but I've noticed that the updated dependencies are pinned to a specific version, which is inconsistent with other dependencies in the package.json files that use caret (^) ranges. I've left comments suggesting to use ^0.3.11 for consistency, which will improve maintainability.

_{Note: Security Review has been skipped due to the limited scope of the PR.}

[gemini-code-assist]

To maintain consistency with other dependencies in this file, which use caret (^) version ranges (e.g., @google-cloud/storage), this dependency should also use a caret. This ensures a consistent dependency management strategy across the project.

Suggested change

	"@a2a-js/sdk": "0.3.11",
	"@a2a-js/sdk": "^0.3.11",
