feat: add home timeline command

Add `bird home` command to fetch the authenticated user's home timeline.

- Supports "For You" feed (default) and "Following" feed (--latest)
- Uses HomeTimeline and HomeLatestTimeline GraphQL operations
- Includes count option (-n), JSON output, and pagination

Usage:
  bird home           # Get "For You" feed
  bird home --latest  # Get "Following" (chronological) feed
  bird home -n 50     # Fetch 50 tweets
