feat(cli): analyze report actions

[quanruzhuoxiu]

Summary

• add midscene analyze report.html with optional output and overwrite flags
• export every successful report action as one standalone, loadable UI Action YAML file
• persist generated XPath cache metadata in new reports and fall back to locatedPixelBbox for historical reports
• skip failed actions and terminal Finished markers

Stack dependency

Depends on #2910, which introduces aiAct(..., { loadExtraActions }) and the one-operation-per-file UI Action protocol.
