Project index reset when at last index

[mbn-code]

This pull request includes several changes to the projectCommand function in the src/commands/project_cmd.cpp file to improve its functionality and readability. The most important changes include fixing the index initialization, ensuring the index resets when it exceeds the number of projects, and moving the index increment to the end of the function.

Improvements to index handling:

• src/commands/project_cmd.cpp: Changed the initialization of the index variable from -1 to 0 to avoid starting with an invalid index.
• src/commands/project_cmd.cpp: Added a check to reset the index to 0 if it exceeds the number of projects, ensuring that the index stays within bounds.
• src/commands/project_cmd.cpp: Moved the increment of the index variable to the end of the function to ensure it is incremented only after a project is successfully processed.
