Add run Command with --reload Option for Automatic Project Reloading

[darixsamani]

Enhance the CLI by adding a new run command that supports a --reload flag. This will allow automatic reloading of the Salvo project whenever code changes are detected, improving the development workflow by eliminating the need for manual restarts.

Proposed Features:

• salvo run command to start the project.
• --reload flag to enable automatic reloading on code changes.

This feature would streamline development and bring Salvo in line with common practices found in other frameworks.
