Changes:
1. browser-cookie3 now in default deps (no separate pip install)
2. install --env=auto now auto-imports cookies on local computers
3. install auto-detects EXA_API_KEY from environment variables
4. install.md cut from 100 lines to 60 lines — two steps not five
Before: pip install → agent-eyes install → 'want search?' → 'want cookies?' → configure each
After: pip install → agent-eyes install (does everything automatically) → only ask about what's missing
Docker clean-room test: all passing, 0 bugs.
