Feature request: Add viewport size parameters to browser_navigate command

Feature Request: Viewport Size Configuration in browser_navigate

Description

I'd like to suggest adding viewport size configuration parameters to the browser_navigate command. Currently, there's no direct way to specify the browser viewport dimensions when navigating to a URL. Adding this capability would enhance testing flexibility, especially for responsive designs.

Use Cases

• Testing responsive designs across different screen sizes (mobile, tablet, desktop)
• Ensuring consistent screenshots/snapshots across environments
• Creating more realistic examples for documentation
• Simplifying test workflows by setting viewport dimensions at navigation time

Proposed Implementation

Add optional parameters to the browser_navigate function:

• width: The viewport width in pixels (default could remain as current implementation)
• height: The viewport height in pixels (default could remain as current implementation)

Example usage:

{
  `url`: `https://example.com`,
  `width`: `1920`,
  `height`: `800`
}

- Page URL: https://example.com/
- Page Title: Example Domain
- Page Snapshot
```yaml
- document [ref=s1e2]:
  - heading "Example Domain" [level=1] [ref=s1e5]
  - paragraph [ref=s1e6]: This domain is for use in illustrative examples in documents. You may use this domain in literature without prior coordination or asking for permission.
  - paragraph [ref=s1e7]:
    - link "More information..." [ref=s1e8]:
      - /url: https://www.iana.org/domains/example

Benefits

1. Flexibility: Allows testing across different device form factors with a single command
2. Efficiency: Reduces the need for separate viewport adjustment commands
3. User Experience: More intuitive for demonstrating responsive behaviors
4. Consistency: Provides standardized viewport control across different sessions

Implementation Complexity

This feature should be relatively straightforward to implement as Playwright already supports viewport size manipulation through its built-in APIs (page.setViewportSize() method).

I'd be happy to provide more details or collaborate on implementing this feature if there's interest.

I'll be supportive of the browser_resize command to keep it similar to what end user would do.
