Saurav Panda 9be28bcea1 feat(llm): default ChatBrowserUse to bu-2-0-mini-preview
Adds bu-2-0-mini-preview as an accepted model id and makes it the
constructor default, so a bare ChatBrowserUse() now routes there.

bu-2-0 is unchanged: still accepted, still documented as the premium
option, and bu-latest still resolves to it. Keeping 'latest' on the
stable line means existing callers pinned to that alias do not silently
move onto a preview model; only the bare-constructor default moves.

Pricing is registered alongside the model so cost tracking does not
silently report $0 for what is now the default. This model has no cache
discount, so cached reads bill at the input rate.

Examples, README and the model reference are updated to the new default.
The model reference also claimed bu-latest resolved to bu-1-0, which has
not been true since bu-2-0 shipped; corrected here.

Getting Started Example 2: Form Filling
This example demonstrates how to:
- Navigate to a website with forms
- Fill out input fields
- Submit forms
- Handle basic form interactions
This builds on the basic search example by showing more complex interactions.
Setup:
1. Get your API key from https://cloud.browser-use.com/new-api-key
2. Set environment variable: export BROWSER_USE_API_KEY="your-key"
