Add supabase studio command

[jsj]

What kind of change does this PR introduce?

Feature - Adds a new CLI command supabase studio to open Supabase Studio directly from the terminal

What is the current behavior?

Currently, users need to manually open their browser and navigate to the Supabase Studio dashboard.

What is the new behavior?

This PR adds a new studio command that automatically opens the Supabase Studio dashboard in the user's default browser. The command:

• Works cross-platform (macOS, Windows, and Linux)
• Uses the appropriate system command to open the browser (open for macOS, start for Windows, xdg-open for Linux)
• Provides feedback to the user by displaying the URL being opened
• Handles errors gracefully with descriptive error messages

Example usage:

supabase studio

This opens the hosted dashboard and not local studio. Is that your intention?

It might be a good idea to support --local and --linked flag to distinguish these use cases.

Yeah this was wrong the goal is to open the local studio url, this comes from using Windsurf, Cursor it will hallucinate this command to go adjust settings only available in the Studio
