Greptile Summary

This bug-fix PR updates capture and replay behavior along with several DevTools panels, runner controls, trace processing utilities, and their tests.

• Distinguishes removed attributes from present empty attributes during DOM replay.
• Synchronizes replayed form properties and boolean attributes with captured mutations.
• Improves runner capability handling, workbench presentation, trace transcript generation, and UID behavior.
• Expands unit and UI coverage for the corrected paths.

Confidence Score: 4/5

The PR should not merge until real checked="false" attribute mutations can be distinguished from synthetic unchecked-state records.

The current decoder still maps every checked record carrying "false" to an absent attribute and false property, even though the collector can produce that identical record when a page sets the present HTML attribute checked="false".
