feat: Add infrastructure cost optimization opportunity finder

[DevMuhdishaq]

Closes #938

Summary

Adds a complete cost optimization framework that automatically identifies, prioritizes, and reports on cloud infrastructure cost savings opportunities. The system detects idle resources, over-provisioned instances, reserved instance opportunities, and savings plan recommendations.

Changes

• Create infrastructure/scripts/find-optimizations.sh - Main scanning script that identifies cost optimization opportunities
• Create infrastructure/scripts/generate-opportunity-report.py - Generates prioritized markdown reports from scan data
• Create infrastructure/docs/cost-opportunities.md - Documentation and auto-generated report location
• Add test data file to validate report generation

Key Features

• Idle resource detection: Identifies running instances with <10% CPU utilization and unattached storage volumes
• Over-provisioned instance detection: Analyzes CPU/memory usage to recommend rightsizing opportunities
• Reserved Instance (RI) analysis: Calculates potential savings from purchasing RIs for steady-state workloads (37.5% savings vs on-demand)
• Savings plan recommendations: Suggests optimal savings plan commitments for consistent compute and serverless spend
• Prioritization: Ranks opportunities by impact (HIGH/MEDIUM/LOW) with clear implementation timelines
• AWS-native integration: Works with AWS CLI out-of-the-box, includes simulation mode for other clouds
• Multi-format output: Generates JSON, CSV, and markdown reports

Estimated Savings (Simulation Mode)

The framework identifies $685+ in potential monthly savings from the simulated scan, with high-priority items that deliver immediate value.

Testing

• Verified script structure and report generation logic
• Tested markdown report creation with sample data
• Confirmed all files are in the correct locations as specified

Usage

# Make scripts executable
chmod +x ./infrastructure/scripts/find-optimizations.sh
chmod +x ./infrastructure/scripts/generate-opportunity-report.py

# Run full scan and generate reports
./infrastructure/scripts/find-optimizations.sh

Reports are automatically generated in:

• infrastructure/.cost-optimizations/ - Raw JSON/CSV data and dated reports
• infrastructure/docs/cost-opportunities.md - Latest consolidated report
