Joseph Savona b16b768fbd [compiler] Feature flag cleanup (#35825) 
Cleans up feature flags that do not have an active experiment and which
we don't currently plan to ship, one commit per flag. Notable removals:
* Automatic (inferred) effect dependencies / Fire: abandoned due to
early feedback. Shipped useEffectEvent which addresses some of the
use-cases.
* Inline JSX transform (experimented, not a consistent win)
* Context selectors (experimented, not a sufficient/consistent win given
the benefit the compiler already provides)
* Instruction Reordering (will try a different approach)

To decide which features to remove, I looked at Meta's internal repos as
well as eslint-pugin-react-hooks to see which flags were never
overridden anywhere. That gave a longer list of flags, from which I then
removed some features that I know are used in OSS.

eslint-plugin-react-compiler

ESLint plugin surfacing problematic React code found by the React compiler.

Installation

You'll first need to install ESLint:

npm i eslint --save-dev

Next, install eslint-plugin-react-compiler:

npm install eslint-plugin-react-compiler --save-dev

Usage

Flat config

Edit your eslint 8+ config (for example eslint.config.mjs) with the recommended configuration:

+ import reactCompiler from "eslint-plugin-react-compiler"
import react from "eslint-plugin-react"

export default [
    // Your existing config
    { ...pluginReact.configs.flat.recommended, settings: { react: { version: "detect" } } },
+   reactCompiler.configs.recommended    
]

Legacy config (.eslintrc)

Add react-compiler to the plugins section of your configuration file. You can omit the eslint-plugin- prefix:

{
    "plugins": [
        "react-compiler"
    ]
}

Then configure the rules you want to use under the rules section.

{
    "rules": {
        "react-compiler/react-compiler": "error"
    }
}

Rules

TODO: Run eslint-doc-generator to generate the rules list.
