fix(create-gen-app): update tests to match camelCase variable naming

Fix test assertions to align with camelCase variable extraction (e.g.,
projectName instead of PROJECT_NAME). Also fix cache test spy issue.

Changes:
- Update extractVariables tests to expect camelCase variable names
- Fix promptUser tests to use correct answer key names (fullName, moduleDesc)
- Update cloneRepo tests to allow --depth 1 flag in git clone commands
- Fix replaceVariables tests to use camelCase answer keys
- Replace execSync spy in cache.test.ts with console.log assertion to
  avoid "Cannot redefine property" error

All tests now correctly validate the camelCase variable naming convention
used throughout the codebase.
