Add EscalationPolicy to AgentEnvironment

Integrate the new EscalationPolicy pattern into the AgentEnvironment
so it's available to components that handle escalations. The policy
evaluates blocker reasons to classify escalation types and determines
urgency based on project state.

- Add escalationPolicy parameter to AgentEnvironment with default
- Update AgentEnvironmentFactory to accept optional EscalationPolicy
- Use DefaultEscalationPolicy as the default implementation
