Subject: [PATCH 1/9] Add getRootNode to fabric fragment instance (#34544)

Stacked on #34533 for root fragment handling

This is the same approach as DOM, where we call getRootNode on the
parent.

Tests are in react-native using Fantom.

Subject: [PATCH 2/9] Add getClientRects to fabric fragment instance (#34545)

Stacked on #34544

We only have getBoundingClientRect available from RN currently. This
should work as a substitute for this case because the equivalent of
multi-rect elements in RN is a nested Text component. We only include
the rects of top-level host components here so we can assume that
calling getBoundingClientRect on each child is the same result.

Tested in react-native with Fantom.

Subject: [PATCH 3/9] [playground] Config panel quality fixes (#34611)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixed two small issues with the config panel in the compiler playground:
1. Object descriptions were being confined in the config box and most of
it would not be visible upon hover
2. Changed it so that "Applied Configs" would only display a valid set
of configs, rather than switching between "Invalid Configs" and the set
of options. This would be less visually jarring for users as the Output
panel already displays errors. Additionally, if users want to see the
list of config options but have a currently broken config, they would
previously not know how to fix it.

Object hover before:

src="https://github.com/user-attachments/assets/b2ddec2f-16ba-41a1-be1f-96211f46764c"
/>
Hover after:
<img width="702" height="481" alt="Screenshot 2025-09-26 at 10 40 37 AM"
src="https://github.com/user-attachments/assets/dc713a22-4710-46a8-a5d7-485060cc9074"
/>

Applied Configs always displays the last valid set of configs:

Subject: [PATCH 7/9] [eprh] Remove hermes-parser (#34719)

We will be focusing eslint-plugin-react-hooks as the primary OSS-only
package for our lint plugin. eslint-plugin-react-compiler will remain as
a Meta only package as some limitations of our internal infra require us
to use packages that aren't widely adopted by the rest of the industry.

This PR removes `hermes-parser`, which was meant to support parsing Flow
syntax.

Subject: [PATCH 8/9] [compiler] Update for Zod v3/v4 compatibility (#34717)

Partial redo of #34710. The changes there tried to use `z.function(args,
return)` to be compatible across Zod v3 and v4, but Zod 4's function API
has completely changed. Instead, I've updated to just use `z.any()`
where we expect a function, and manually validate that it's a function
before we call the value. We already have validation of the return type
(also using Zod).

Subject: [PATCH 9/9] React DevTools 7.0.0 (#34692)

[Preview](https://github.com/eps1lon/react/blob/sebbie/09-28-react_devtools_7.0.0/packages/react-devtools/CHANGELOG.md#700)

Suspense tab is omitted since that's gated on Canary or 19.3.

Will draft a separate blog post for suspended by and open-in-editor
instructions while the extension is in review.
