Create Detection Logic Package

[josecelano]

Parent Issue: #113 - Create Dependency Installation Package for E2E Tests
Depends On: None (first phase)
Epic: #112 - Refactor and Improve E2E Test Execution

Overview

Create the package structure and implement detection logic to check if development dependencies (cargo-machete, OpenTofu, Ansible, LXD) are installed.

This is Phase 1 of 4 for building the dependency installation package.

Objectives

• Create packages/dependency-installer/ structure following packages/linting/ pattern
• Define ToolDetector trait for detection abstraction
• Implement 4 detector structs (CargoMachete, OpenTofu, Ansible, LXD)
• Create DependencyManager to coordinate detectors
• Add comprehensive unit tests with mocked commands
• Set up tracing for observability

Key Components

ToolDetector Trait:

trait ToolDetector {
    fn name(&self) -> &str;
    fn is_installed(&self) -> Result<bool, DetectionError>;
}

4 Detector Implementations:

• CargoMacheteDetector - checks cargo machete --version
• OpenTofuDetector - checks tofu --version
• AnsibleDetector - checks ansible --version
• LxdDetector - checks lxc --version

DependencyManager:

• Coordinates all detectors
• Provides check_all() method returning status for all tools

Acceptance Criteria

• Pre-commit checks pass
• Package structure follows linting package pattern
• ToolDetector trait is well-defined
• All 4 detectors are implemented with proper error handling
• DependencyManager works correctly
• Unit tests cover all detectors with mocked commands
• Logging provides clear visibility

Time Estimate

2-3 hours
