feat: experimental chrome-devtools CLI (#1100)
This PR enables an alternative CLI interface for Chrome DevTools MCP.
`chrome-devtools` can be used in shell scripts to automate the Chrome
DevTools MCP session running as a daemon process. Currently, a single
session is shared between all `chrome-devtools` calls. All tools
available by default are included into the CLI.
Examples:
```bash
❯ chrome-devtools navigate_page --url https://example.com
Successfully navigated to https://example.com.
## Pages
1: https://example.com/ [selected]
❯ chrome-devtools lighthouse_audit
## Lighthouse Audit Results
Mode: navigation
Device: desktop
URL: https://example.com/
### Category Scores
- Accessibility: 96 (accessibility)
- Best Practices: 96 (best-practices)
- SEO: 80 (seo)
### Audit Summary
Passed: 30
Failed: 4
Total Timing: 4107.22ms
