Greptile Summary

Updated MCP server types to use the properly exported Page type from @browserbasehq/stagehand v3.0.2, replacing the placeholder any types in StagehandSession and BrowserSession.

• Upgraded @browserbasehq/stagehand dependency from ^3.0.1 to ^3.0.2
• Added @types/node ^24.10.1 to devDependencies (likely pulled in as transitive dependency upgrade)
• Replaced page: any with page: Page in src/types/types.ts (lines 9 and 25)
• Updated lockfile to reflect dependency changes

This is a pure type safety improvement with no runtime behavior changes. The Page type was newly exported in stagehand 3.0.2, enabling proper TypeScript typing for page objects retrieved via stagehand.context.pages()[0].

Confidence Score: 5/5

• This PR is completely safe to merge - it only improves type safety with no runtime changes
• Score reflects that this is a straightforward type safety improvement: (1) minor semver patch version bump of stagehand from 3.0.1 to 3.0.2, (2) replacing any types with proper Page imports, (3) no logic changes whatsoever, (4) the Page type aligns with existing usage pattern where page objects are retrieved from stagehand.context.pages()[0], and (5) lockfile updates are clean with no unexpected dependency changes
• No files require special attention
