Refactor API: Move automate to agent client and remove extract.schema (#5)

## Summary
- Moves automate functionality behind a new `agent` client
(`tabs.agent.automate()`)
- Removes `extract.schema()` method entirely
- Updates all documentation, examples, and tests to reflect the new API

## Changes
- **New Agent Client**: Created `Agent` class to handle automation
- **API Simplification**: Removed `extract.schema()` method and
`ExtractSchemaOptions` type
- **Updated Documentation**: README and examples now reflect the new API
- **Test Coverage**: All 233 tests pass

## Migration Guide
### Before
```typescript
for await (const event of tabs.automate.execute(task, options)) {
    ...
}

const schema = await tabs.extract.schema(url, { instructions: "..." });
```

### After
```typescript
for await (const event of tabs.agent.automate(task, options)) {
    ...
}

// extract.schema() removed - use predefined schemas instead
```
