How `resolve_device()` works

• Alias normalization: Strips whitespace, converts to lowercase, maps spaces to hyphens, and resolves the name through DEVICE_ALIASES in src/loki/engine/devices.py.
• Playwright catalog lookup: If the name is not in DEVICE_ALIASES, resolve_device() performs a case-insensitive exact match (and then substring match) against Playwright's full playwright.sync_api.devices dictionary.
• Orientation (--orientation portrait | landscape): In landscape mode, LOKI first checks if Playwright defines a native <Device> landscape profile; otherwise it clones the device descriptor and swaps viewport.width and viewport.height.
• Automatic Mobile Layout Audit: Enabling --device / -m automatically activates the Mobile Layout Overflow detector (scrollWidth > innerWidth, off-screen interactive buttons/links/inputs, and tiny touch targets < 24×24 px).
