feat: implement comprehensive Period Management Framework (issue #112)
Complete period lifecycle management system including: - PeriodManager class with full lifecycle operations - Period status management (open/calculating/closed) with validation - Period overlap detection and conflict resolution - Comprehensive cost calculation and aggregation engine - Loss carried forward calculations between periods - Period closure validation with audit trails - Current period detection and auto-creation utilities CLI Integration: - Complete period command suite (create, list, show, calculate, status, close, current) - Professional CLI output with detailed formatting - Comprehensive error handling and validation - Date filtering and status filtering capabilities Testing: - 25 core PeriodManager tests covering all functionality - 24 CLI command tests ensuring proper integration - Edge case testing for complex scenarios - 49 total tests passing with comprehensive coverage Database Integration: - Utilizes existing cost_periods schema from FinanceModels - Full SQLite integration with proper constraints - Performance-optimized indexes and queries - Seamless integration with existing cost tracking system 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

- Period overlap validation and conflict resolution

- Automatic period calculations and data aggregation
|

- Loss carried forward calculations

- Period closure validation and audit trails

The framework supports the complete period lifecycle:

1. OPEN: Period is created and active for cost tracking

2. CALCULATING: Period is being processed for cost allocation

3. CLOSED: Period is finalized with all calculations complete
