fix(test): stop use-input test from leaking a global stdin mock

[kevincodex1]

The use-input.test.ts added in #1198 broke the full bun test run two ways:

1. It imported @testing-library/react-hooks, which was never installed and is React 16/17/18-only (incompatible with this repo's React 19), so the file errored on load.
2. Its top-level vi.mock('./use-stdin.js', …) registered a module mock that leaks across every later file in the same bun test process. The fake eventEmitter's .on was a no-op, so useInput silently registered no listener and dropped all keystrokes — surfacing as timeouts in MonitorPermissionRequest and the agent-menu/wizard TextInput tests (which passed in isolation but failed in the full suite).

Rewrite the test to inject the stdin handle via StdinContext.Provider (no leaking global mock) and render through the real ink root (no @testing-library/react-hooks). Drop the now-dead react-hooks and react-test-renderer devDependencies and reconcile the lockfile.

Full suite: 3429 pass, 0 fail (was 9 fail + 1 error).

📝 Walkthrough

Walkthrough

This PR removes the @testing-library/react-hooks and react-test-renderer dev dependencies and rewrites the useInput hook test suite with a custom test harness that mounts the hook in a real React root with StdinContext.Provider injection, replacing fake-timer assertions with real async timing.

Changes

Test Harness Migration

Layer / File(s)	Summary
Dependency cleanup package.json	Remove @testing-library/react-hooks and react-test-renderer from devDependencies.
Test harness and imports src/ink/hooks/use-input.test.ts	New test imports replace testing-library mocks; add Bun root/PassThrough stream creation; define fake StdinContext value with setRawMode spy and real EventEmitter; implement renderProbe helper that mounts Probe component and exposes rerender/unmount; switch from fake timers to async tick() using Bun.sleep(5); rework suite setup/teardown to use bun:test mock spy lifecycle.
Test case implementations src/ink/hooks/use-input.test.ts	Rewrite five test cases to async form: verify setRawMode(true) on mount when active; verify no call when inactive; verify deferred setRawMode(false) after unmount tick; verify cancelled deferred reset on true → false → true transition; verify true → false transition eventually calls deferred reset.

🎯 2 (Simple) | ⏱️ ~10 minutes

A test harness springs to life with a real React root so true,
No fake timers needed, just Bun.sleep and tick() do,
The hook now renders honestly, with context injected just right,
Each test case hops and bounds in async delight,
What once was mocked, now breathes with real-time might! 🐰✨
