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".

Files Needing Attention: packages/app/src/components/browser/boolean-attribute.ts, packages/script/src/index.ts, packages/script/src/mutations.ts

Important Files Changed

Filename	Overview
packages/app/src/components/browser/boolean-attribute.ts	Adds boolean-attribute decoding that fixes ordinary literal-false attributes but still conflates real checked="false" mutations with synthetic unchecked-state records.
packages/app/src/components/browser/snapshot.ts	Correctly distinguishes attribute removal from empty values and synchronizes replayed form state while preserving dirty input text.
packages/script/src/mutations.ts	Serializes removed attributes as absent values while preserving empty and literal string values for replay.
packages/script/src/index.ts	Emits synthetic field-state mutations, including checkbox property state using the same checked mutation shape as real attribute changes.
packages/app/test-ui/workbench/player/snapshot.test.ts	Adds broad replay coverage for boolean attributes, non-boolean removals, empty values, and pristine versus dirty fields.
