Exclude tests from the Metrics/ClassLength Rubocop offfense
since the plan is to rewrite the test suite in RSpec. At that time
many of the Rubocop exclusions will be removed.

This refactoring streamlines the Git::Status class by decomposing
its responsibilities, resulting in cleaner, more focused components:

* `StatusFile`: The inner data responsibilities was moved to its
  own class.
* `StatusFileFactory`: A new private factory was created to
  encapsulate all the logic for executing git commands and parsing
  their output into StatusFile objects.

I think the result is more readable and maintainable code.

The Git::Log class had grown to over 150 lines, making it difficult
to read and maintain. This refactoring simplifies the internal
implementation to improve its structure and reduce its size to under
100 lines, without altering the public API.

The primary motivations were to enhance readability and make the
class easier to extend in the future.

The key changes include:

- Consolidated all query parameters from individual instance
  variables into a single `@options` hash to simplify state
  management.
- Replaced repetitive builder methods with a concise `set_option`
  private helper, reducing code duplication.
- Centralized the command execution logic into a single
  `run_log_if_dirty` method to ensure consistent behavior.
- Simplified the deprecated Enumerable methods by using a helper
  for warnings and safe navigation (`&.`) for cleaner error handling.
- Modernized the nested `Git::Log::Result` class to use
  `Data.define`, leveraging Ruby 3.2+ features to create a more
  concise and immutable result object.
