Refactor to re-enable disabled SwiftLint rules

[bguidolim]

Context

SwiftLint was introduced in the project (PR pending). Several structural rules were disabled because the existing codebase has violations that require significant refactoring to fix. These should be re-enabled incrementally.

Disabled rules to re-enable

cyclomatic_complexity (25 violations when last checked)

Functions in Configurator.swift, CLIOutput.swift, GlobalSyncStrategy.swift, and others have complexity 11-31 (default threshold: 10). Requires breaking complex functions into smaller, focused methods.

type_body_length (24 violations when last checked)

Structs in both Sources (11) and Tests (13) exceed 250-line bodies. Sources violations concentrated in Configurator, CLIOutput, ExternalPackManifest. Test structs naturally grow large — consider splitting test files or adjusting thresholds for tests.

file_length (22 violations when last checked)

Files exceeding 400 lines. Directly correlated with type_body_length — fixing one will largely fix the other.

Approach

1. Address cyclomatic_complexity first — it's the most impactful for code quality
2. type_body_length and file_length will improve as complex functions are extracted
3. Consider different thresholds for test files vs source files
4. Re-enable each rule in .swiftlint.yml as violations are cleared
