feat(mac-crafter): New logging.

[i2h3]

• Write log messages to standard output in terminal environment.
• Write log messages to unified logging system of macOS (see Console app of macOS, filter for "mac-crafter" process and "com.nextcloud.mac-crafter" subsystem).
• Write log messages to a log file (located in ~/Library/Logs/mac-crafter).
• All simultaneously.
• Standard output and errors from child processes launched are captured, too. In example all the KDE Craft output which is run by mac-crafter.

Pull request overview

This PR introduces a comprehensive logging system for mac-crafter that replaces direct print() statements with a centralized logging facility. The new system simultaneously writes to standard output, the macOS unified logging system, and a log file in ~/Library/Logs/mac-crafter.

Key Changes:

• Introduces a new Log actor with info() and error() methods for centralized logging
• Enhances Shell.swift to capture and route child process stdout/stderr through the logging system
• Updates all direct print() calls throughout the codebase to use the new logging API
