Greptile Summary

Updates @browserbasehq/stagehand dependency from version 3.0.3 to 3.0.8, a minor version bump within the same major version.

Key changes:

• Stagehand version updated from ^3.0.3 to ^3.0.8 in package.json:49
• Lockfile updated with new transitive dependencies including enhanced Google Vertex AI support (@ai-sdk/google-vertex@3.0.97), updated Anthropic SDK, and new auth libraries
• New peer dependency constraint for zod updated to ^3.25.76 || ^4.2.0 (was 3.25.67)
• Removes bufferutil peer dependency from stagehand (now optional)
• Adds UUID package to stagehand's direct dependencies

This is a routine dependency update that brings bug fixes and improvements from the upstream stagehand library. No source code changes are required, indicating the update maintains backward compatibility.

Confidence Score: 5/5

• Safe to merge - routine dependency update with no breaking changes
• This is a straightforward minor version bump (3.0.3 → 3.0.8) within the same major version, maintaining semantic versioning compatibility. No source code changes were needed, confirming backward compatibility. The lockfile changes only add new optional AI provider packages and update transitive dependencies, with no removals of critical dependencies. The peer dependency changes are relaxations (expanding zod support), not restrictions.
• No files require special attention
