refactor: rename API methods for improved clarity

[quanru]

Summary

This PR refactors the Midscene API by renaming key methods for improved clarity and consistency:

• aiAction() → aiAct() - More concise and clear naming
• logScreenshot() → recordToReport() - Better reflects the method's purpose

Breaking Changes

⚠️ Breaking Change: The following methods have been renamed:

• aiAction() is now aiAct()
• logScreenshot() is now recordToReport()

Backward Compatibility: The old aiAction() method is kept as a deprecated wrapper to maintain backward compatibility. Users should migrate to aiAct() when convenient.

Changes

• ✨ Renamed aiAction() to aiAct() in packages/core/src/agent/agent.ts
• ✨ Renamed logScreenshot() to recordToReport() in agent implementation
• 🔄 Added deprecation wrapper for aiAction() with JSDoc warning

Web Integration

• 🔧 Updated Playwright fixture to support new method names

Documentation

• 📝 Updated all English documentation (15 files)
