This pull request introduces a new command, sv-status-all, to the Termux services management suite. The command provides an overview of all services, including their enabled/disabled status and runtime state. The changes include the implementation of the command, updates to the Makefile for installation and uninstallation, and documentation in the README.md.

New Command Implementation:

• sv-status-all script: Added a new script to display the status of all services in $SVDIR. It checks each service's directory for a down file to determine if the service is enabled or disabled and uses sv status to fetch the runtime state.

Build System Updates:

• Installation in Makefile: Updated the install target to include the new sv-status-all script, ensuring it is installed to the appropriate directory.
• Uninstallation in Makefile: Updated the uninstall target to remove the sv-status-all script during cleanup.

Documentation Enhancements:

• README.md: Added a new section documenting the sv-status-all command, including its purpose, usage, and output format. This provides clear guidance to users on how to utilize the new functionality.
