Create the base project structure for CLI, engine, parser, evaluator, and config

[Matographo]

Summary

Set up the initial module layout for CLI, lexer, parser, AST or IR, evaluator, renderer, rules, settings, and cache.

Why

A clean project skeleton reduces churn once implementation starts and helps keep performance-sensitive concerns separated.

Deliverables

• Base repository layout
• Build and test entry points
• Clear module boundaries

Acceptance Criteria

• The repository has a clear module layout
• Core concerns are separated cleanly
• Basic build and test skeletons exist

Dependencies

• Depends on Specify CLI behavior, inspection commands, and exit codes #2 for CLI scope clarity
