import keyboard crashes on macOS in examples/re_book/1_brain_evolution.py

Running the example in the main branch aborts immediately with:

Assertion failed: (range.location + range.length <= dataLength), function __CFDataValidateRange, file CFData.c, line 235.
(exit code 134, SIGABRT — no Python traceback)

Reproduction: uv run python -c "import keyboard" — crashes on its own, independent of the example.

Environment:

• macOS 13.6.7 (Darwin 22.6.0), arm64 (Apple Silicon)
• Python 3.12.9
• keyboard 0.13.5 (pulled in via ariel's deps)

Notes:

• keyboard is imported as kb at examples/re_book/1_brain_evolution.py:20 but never actually used in that file — a simple fix is to drop the import.
• More broadly, the keyboard package is a bad cross-platform dep: it's effectively unmaintained, needs root on macOS/Linux to work, and has open issues about this exact CoreFoundation assertion. Consider replacing it with pynput or removing it from ariel's dependencies if it's only used in examples.
