File System Validator

Build a utility that validates the presence of required files and directories in a project structure.

Capabilities

Path Existence Validation

• Given path "/config/app.json" that exists, validatePath returns true @test
• Given path "/src" that exists, validatePath returns true @test
• Given path "/missing.txt" that does not exist, validatePath returns false @test

Batch Validation

• Given paths ["/package.json", "/README.md"], both existing, validatePaths returns [true, true] @test
• Given paths ["/existing.txt", "/missing.txt"], only first exists, validatePaths returns [true, false] @test
