Summary of Changes

Hello @AliiiBenn, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces version 0.3.0 of the Excel Toolkit, primarily focusing on a substantial internal refactoring of the command-line interface's command layer. The goal was to enhance the project's architecture by separating CLI concerns from business logic, leading to a more modular, maintainable, and testable codebase. This was achieved by delegating core data manipulation and validation tasks to a new operations layer and centralizing common I/O patterns, all while preserving the existing user experience.

Highlights

• Major Command Layer Refactoring: The core command layer of the Excel Toolkit has undergone a complete refactoring, moving business logic to a dedicated operations layer. This significantly improves separation of concerns and code organization.
• Significant Code Reduction: This refactoring resulted in a reduction of 1,640 lines of code across all commands, representing an average 39% decrease in command file sizes. The largest command, validate.py, saw an 80% reduction.
• New Helper Functions and Unified I/O: Two new helper functions, read_data_file() and write_or_display(), have been introduced in excel_toolkit/commands/common.py to centralize and unify file input/output operations, replacing approximately 845 lines of duplicated code.
• No Breaking Changes for Users: Despite the extensive internal refactoring, all CLI commands maintain 100% backward compatibility, ensuring no disruption for existing users.
• Detailed Refactoring Specification: A comprehensive PHASE_3_DETAILED_SPEC.md document has been added, outlining the objectives, current state analysis, refactoring strategy, implementation roadmap, testing strategy, and risk assessment for this major architectural change.

Code Review

This pull request introduces a significant refactoring of the command layer, as detailed in the new release notes and specification documents. The version is also bumped to v0.3.0. While the changes are well-documented within the added markdown files, the pull request title "Update" and the empty description are not very descriptive. It would be beneficial for future reviews and for the project's history to have more descriptive PR titles and bodies. The release notes have a minor language inconsistency that should be addressed for clarity.

[gemini-code-assist]

The "Overview" section is written in French, while the rest of the document is in English. For consistency and to ensure the document is accessible to a wider audience, it would be better to have the entire document in a single language, presumably English, like the rest of the file.
