Fixes two open issues and adds tests so neither can come back quietly.

StrictMode: `connected` stuck on `false` (closes #140)

StrictMode runs mount, cleanup and mount again. `useSocketState` subscribed to connection events behind a mount-once guard, so the cleanup removed the subscriptions and the guard stopped them from coming back.

• `useSocketState` now uses a plain effect and syncs `connected` / `connecting` from the socket when it subscribes. This covers `useListener` and `useEmitter`.
• `useAppManager` and `useSubmit` had the same pattern and the same bug (online/focus never updated, cache updates before the first submit were missed). Fixed as well.

CLI crash on startup (closes #142)

Not specific to Node 24. The CLI was built for the browser, so Vite swapped `fs`, `path` and other builtins for an empty stub. Reproduced with the published 9.0.0.

• Build now targets Node and prefers CommonJS entries of bundled dependencies.
• `bin` pointed at the library file instead of the CLI entry, so `npx @hyper-fetch/cli init` would have done nothing once the crash was gone. It now points at `dist/cli.js` under the name `hyper-fetch` (a global install used to expose it as `cli`).
• `init --help` and `generate --help` failed with "argument missing", and top level `--help` / `--version` opened the command picker. Both work now.

Tests

• `packages/react/tests/features/strict-mode/`: runs `useSocketState`, `useListener`, `useEmitter`, `useAppManager` and `useSubmit` under StrictMode. 24 of 29 cases failed before the fix.
• `packages/cli/tests/bundle/bundle.spec.ts`: builds the package and runs the real output with `node` (version, help, a full `init --yes` in a temp project), checks that no builtin is stubbed and that every leftover `require` is installable. Adds about 5 seconds to the CLI test run and needs `@hyper-fetch/core` built first, which CI already does.

Full suites pass locally: react 428, cli 32. Lint and typecheck are clean for both packages.
