Create "Intermesh vs. Other Software" Documentation #15

Overview

Create comprehensive comparison documentation that positions Intermesh within
the broader networking and security ecosystem. This documentation should help
users understand when to choose Intermesh over alternatives and how it
complements existing tools.

Dependencies

This issue depends on completion of issue #13 (README documentation) as it
builds upon the foundational project description.

Documentation Style

Borrow the style and approach of HashiCorp documentation for similar
comparative analysis. HashiCorp excels at fair, technical comparisons that
highlight appropriate use cases for different tools without dismissing
alternatives.

Reference Examples:

• Vagrant vs. Other Software
• Vue.js - Comparison with Other Frameworks
• Nomad vs. Other Software

Goal

Provide a very fair description of how Intermesh fits relative to various
projects in the ecosystem, focusing on technical distinctions, use case
appropriateness, and complementary relationships rather than competitive
positioning.
