feat: add human-like behavioral layer (humanize option)

Bezier mouse curves, per-character typing with mistype simulation,
smooth micro-step scrolling, idle micro-movements between actions.

Supports both sync and async Playwright APIs. Patches page, frame,
context, browser, and Locator class methods.

Two presets: 'default' (normal speed) and 'careful' (slower, deliberate).
Configurable via HumanConfig dataclass / interface with full override support.

Bug fixes (from PR review):
- fill()/clear(): platform-aware select-all (Meta+a on macOS, Control+a elsewhere)
- sync Locator check()/uncheck(): wrap mouse_move in RawMouse-compatible object
- resolve_config(): raise error on unknown preset name
- Lazy-load human.config via __getattr__ in __init__.py
- humanPreset typed as 'default' | 'careful' literal union
- browser.newPage() patches implicit context

Tests: Python 36/36, JS Vitest 34/34, visual Python 17/17, JS 13/13
