With this change, Components panel will display subtree of the Activity. When it is in hidden mode, the subtree will be dimmed. Added Jest tests and a sandbox case to `react-devtools-shell`. Demo: https://github.com/user-attachments/assets/69a2e8d6-585d-4fcd-b57e-e9ae06d0a1b3
Harness for testing local changes to the react-devtools-inline and react-devtools-shared packages.
Development
This target should be run in parallel with the react-devtools-inline package. The first step then is to run that target following the instructions in the react-devtools-inline README's local development section.
The test harness can then be run as follows:
cd packages/react-devtools-shell
yarn start
Once you set both up, you can view the test harness with inlined devtools in browser at http://localhost:8080/
