Mofei Zhang 1d4cbaffb5 [compiler][patch] Emit unary expressions instead of negative numbers

This is a babel bug + edge case.

Babel compact mode produces invalid JavaScript (i.e. parse error) when given a `NumericLiteral` with a negative value.

See https://codesandbox.io/p/devbox/5d47fr for repro.

As a followup, we could change our test infra parse babel options (e.g. a babel transform options pragma) which could let us track regressions. We may add an "exhaustive" mode to the compiler test runner to test (1) different babel options and (2) commonly used versions.

babel-plugin-react-compiler

React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.

This package contains the React Compiler Babel plugin use in projects that make use of Babel. You can find instructions for using this plugin here: https://react.dev/learn/react-compiler
