GHL Browser Agent — Zero-touch GoHighLevel Automation
Implements PRD_ADVANCED_BROWSER_USE.md Story 5: GHL Dashboard Automation

Capabilities:
  - Login with session cookie persistence (avoids re-login)
  - Activate/deactivate workflows
  - Read contact pipeline data
  - Add team members to sub-accounts
  - Check location settings

Security:
  - Credentials loaded from config/secrets.env ONLY
  - Session cookies stored at data/browser_sessions/ghl_session.json
  - Screenshots saved as evidence at data/screenshots/ghl_[step]_[ts].png
  - Credentials never appear in output files or logs
