Add Motherboard Info Collection and Storage Total Enhancements

Overview

This PR adds comprehensive motherboard information collection and enhances storage reporting capabilities in our hardware reporting tool.

Key Changes

• Implemented motherboard information collection using dmidecode
• Added storage totals calculation and display
• Enhanced system summary display
• Added TOML serialization for new data fields

New Features

Motherboard Information

• Collects manufacturer, product name, version, serial number
• Reports features and location information
• Integrates with existing system summary
• Adds to TOML configuration output

Storage Enhancements

• Calculates total storage across all devices
• Displays human-readable storage totals
• Shows individual drive contributions
• Reports capacity in TB with precision

Implementation Details

/// Motherboard information struct
struct MotherboardInfo {
    manufacturer: String,
    product_name: String,
    version: String,
    serial: String,
    features: String,
    location: String,
    type_: String,
}

Sample Output

System Summary:
==============
Motherboard: Supermicro X13DEG-OAD v1.01 (S/N: OM237S046931)
Storage: 3.8 TB (Total: 3.84 TB)
Storage Devices: 960GB + 960GB + 960GB + 960GB

Testing

• Tested on various server configurations:
  • SuperMicro X13 platform
  • Dell PowerEdge systems
  • HPE ProLiant servers
• Verified TOML output format
• Checked dmidecode parsing accuracy
• Validated storage calculations

Dependencies

• Requires dmidecode (already a dependency)
• Uses existing lsblk functionality
• No new external dependencies added

Documentation

• Updated code comments for new functions
• Added struct field documentation
• Included sample output in README

Backwards Compatibility

• Maintains existing TOML format
• Adds new fields non-disruptively
• Preserves all existing functionality

Notes for Reviewers

• Focus on error handling in dmidecode parsing
• Check storage calculation precision
• Verify NUMA topology integration
• Review naming conventions
