Improved CLI experience when linking and creating environment variables ​‍

Here are some of the key improvements introduced in version 50.0.0:

• After successfully linking a project, the CLI now prompts you to pull your Project’s Environment Variables to keep your local setup aligned with your deployed configuration.

• Input for new Environment Variables is now masked during interactive entry

• When connecting to an existing project with link, the CLI now shows an interactive selector if you have fewer than 100 Projects.

• Fixed an issue where vc link --repo would incorrectly prefix project names.

• Commands that support the ls argument now have standardized behavior. Extra or unexpected arguments will consistently produce a clear error and exit early, ensuring predictable and reliable results across all ls commands. This change may require updates to scripts that depended on the previous behavior.
