feat!: ESM-only v2 with tsup + vitest toolchain

BREAKING CHANGE: the package is now ESM-only (no CommonJS build). Consumers
must use `import`; `require()` is no longer supported. Requires Node.js >= 18.

Toolchain modernization:
- Build: rollup + multi-tsc (cjs/es/umd/typings) + generate-esm-wrapper hack
  -> single `tsup` step emitting ESM + type declarations.
- Test: jest + ts-jest + jest.resolver axios hack -> vitest (native ESM,
  no resolver hack). Tests use Node's native FormData/URLSearchParams/Blob
  instead of polyfills, and override read-only globals via defineProperty.
- Lint: eslint 8 (.eslintrc) -> eslint 9 flat config + typescript-eslint 8;
  prettier 2 -> 3.
- TypeScript 4.9 -> 5.9; @types/node 16 -> 26.

change-case dependencies (camel-case/snake-case/header-case) stay on the v4
line: v5 is ESM-only *and* drops the `stripRegexp` option we rely on to
preserve bracketed keys like `user_profile[screen_name]`. An ESM package can
still import these CJS deps.

Supersedes #77 (@types/node bump, which required this TS/jest cascade).
