feat: implement deployment strategies with compartment-based batching

[t0mmylam]

Implements configurable deployment strategies for Skyhook Safe Rollouts with compartment-based batch processing and failure handling.

Features Added

• Three Deployment Strategies: Fixed, Linear, and Exponential batch sizing
• Safety Limits: Only slow down on errors when rollout progress < safetyLimit (default 50%)
• Failure Thresholds: Auto-pause after consecutive batch failures with configurable thresholds
• Pass/Fail Logic: Evaluate batch success based on batchThreshold percentage
• Compartment Integration: Per-compartment batch processing with budget enforcement
• Batch Persistence: Track batch state across reconciles in Skyhook status

Strategy Behavior

• Fixed: Constant batch size throughout rollout
• Linear: Grows by delta each successful batch (initialBatch + n*delta)
• Exponential: Multiplies by growthFactor each successful batch (initialBatch * factor^n)

Implementation Details

• Added BatchProcessingState to track batch progress and failures
• Enhanced Compartment wrapper with batch processing logic
• Integrated batch evaluation into IntrospectSkyhook for proper state management
• Comprehensive unit tests
