@Hypnosphi @claude
chore(deps): adapt build pipeline to @babel/core 8
c4d1424 
- Replace @jetbrains/babel-preset-jetbrains (asserts Babel ^7, no Babel 8
  release) with its inlined equivalent: preset-react, preset-env and
  preset-typescript 8
- Replace preset-env's removed `useBuiltIns: 'usage'` with
  babel-plugin-polyfill-corejs3, excluding core-js own files: Jest
  transforms node_modules, and polyfill imports injected into core-js
  internals create require cycles
- Scope preset-react to non-.ts files: Babel 8 no longer disables JSX
  parsing in .ts files, breaking generics like `<T>(arg: T) => ...`
- Pin preset-react `development: false`: in Babel 8 it defaults to env
  sniffing, leaking jsx-dev-runtime into dist when NODE_ENV is unset
- Opt 16 components out of react-compiler with 'use no memo':
  babel-plugin-react-compiler 1.0.0 crashes on Babel 8 AST for
  destructuring defaults (Babel 8 removed AssignmentPattern from the LVal
  alias), and the latest experimental build fails too. Compiler output is
  byte-identical between Babel 7 and 8 cores for all other files. Remove
  the directives once react-compiler supports Babel 8
- Sync package-lock.json (was out of sync, npm ci failed)

Note: babel-loader was already at 10.1.1 (latest) and supports Babel 8;
it was never the cause of the Storybook build failure.
