Add Cross-Platform Support (macOS & Linux)

[vamsi-op]

Description

Currently, JARVIS only works on Windows (using start commands and Windows-specific apps). Make it cross-platform to work on macOS and Linux.

Current Issues

• Application shortcuts are Windows-only (start chrome, start winword)
• System commands use Windows syntax (shutdown /s /t 30)
• File paths assume Windows structure

Implementation

• Detect OS using platform.system()
• Create platform-specific command dictionaries
• Use subprocess instead of os.system() for better cross-platform support
• Add macOS/Linux equivalent commands
• Update documentation with platform-specific installation instructions

Example Structure

import platform
SYSTEM = platform.system()  # 'Windows', 'Darwin' (macOS), 'Linux'

APPLICATIONS = {
    'google': {
        'Windows': 'start chrome',
        'Darwin': 'open -a Google Chrome',
        'Linux': 'google-chrome'
    }
}

Benefits

• Wider user base
• Better project adoption
• More contributors from different platforms
