Overview

Safety Manager

Coordinates all safety components (budget tracking, rate limiting, content filtering, audit logging) and provides a unified interface.

Examples:

safety = Manager.new(
  daily_budget: 10.0,
  requests_per_minute: 10,
  blocked_patterns: ['password']
)
safety.check_request!(message: "Hello", estimated_cost: 0.01)
