[Feature] Enhance Midscene Reports: Add Playwright timing metrics and optimize page load waits

Background

Currently, Midscene reports provide basic execution time information for Playwright operations, but users have requested more granular timing data to identify performance bottlenecks in automation scripts. Additionally, the default timeout settings for waitForNetworkIdle sometimes cause unnecessary delays, and users want more control over this. Meanwhile, the execution speed of waitForSelector('html') is considered to have room for optimization, which could improve overall script efficiency.

Feature Details

1. Detailed Playwright Timing Display in Midscene Reports

Midscene reports will include the following additional timing information:

• Page load time
• Network request time
• Time spent on specific operations (e.g., clicks, navigation)

2. Configurable waitForNetworkIdle Options

• Users can customize the timeout duration for waitForNetworkIdle via configuration
• Users can opt to completely disable waitForNetworkIdle to adapt to varying network conditions

3. Optimize waitForSelector('html') Speed

• Reduce the waiting time for waitForSelector('html') by adjusting polling strategies or using more efficient selectors

Implementation Plan

1. Modify the Midscene report generation logic to capture and display additional Playwright timing metrics
2. Add configuration options in Midscene.js to control the timeout and enable/disable waitForNetworkIdle
3. Analyze and refactor the implementation of waitForSelector('html') to improve its execution efficiency

Expected Impact

This feature will help users:

• Gain deeper insights into the performance of their automation scripts
• Identify and resolve potential performance issues
• Have greater flexibility in unstable network environments through configurable waitForNetworkIdle
• Experience improved script execution speed through optimized waitForSelector('html')
