fix: correct Lightpanda fallback docs — remove nonexistent PDF/upload/clipboard actions 

Hermes has no browser PDF, file upload, or clipboard tools. The fallback
mechanism only covers commands in _FALLBACK_ELIGIBLE (open, snapshot,
screenshot, eval, click, fill, scroll, back, press, console, errors).
The original docs described Lightpanda's general limitations, not
Hermes's actual behavior.

Hermes drives Lightpanda through `agent-browser` over CDP, the same way it drives local Chrome.
**Automatic Chrome fallback.** Lightpanda doesn't yet cover everything Chrome does, so the integration is non-disruptive: Lightpanda handles the actions it supports, and Hermes transparently retries on Chrome for anything it doesn't. The supported set covers the core agent workflow — navigate, snapshot, click, type, scroll, back, press, and eval. Actions that fall back to Chrome include screenshots (Lightpanda has no graphical renderer), PDF generation, file uploads, and clipboard operations. Because Lightpanda skips visual rendering, `browser_vision` is pre-routed straight to Chrome.
