feat(l4): add AutonomyManager for tiered authorization system (Phase 3)

Implements L4 self-evolution authorization with: Autonomy Levels: - Supervised: All actions require user confirmation - Assisted: Low-risk actions auto-execute, high-risk need approval - Autonomous: Agent decides, only high-impact actions notify Features: - Risk-based action classification (low/medium/high) - Importance threshold for auto-approval - Approval workflow with pending queue - Full audit logging with rollback support - Configurable action permissions per level Security: - High-risk actions ALWAYS require confirmation - Self-modification disabled by default even in autonomous mode - All autonomous actions logged for audit - One-click rollback to any historical state Tests: 30 passing Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

+/**
+ * Autonomy Manager - Tiered authorization system for L4 self-evolution
+ *
+ * Provides granular control over what actions the Agent can take autonomously:
+ * - Supervised: All actions require user confirmation
+ * - Assisted: Low-risk actions execute automatically
+ * - Autonomous: Agent decides when to act and notify
+ *
+ * Security boundaries:
+ * - High-risk operations ALWAYS require confirmation
+ * - All autonomous actions are logged for audit
+ * - One-click rollback to any historical state
+ *
+ * Reference: ZCLAW_AGENT_INTELLIGENCE_EVOLUTION.md §6.4.3
