Fix: make dev_setup.sh cross-platform (Windows & Linux/Mac) — follow-up to #770

[devendra1973]

This PR improves the developer setup script:

• Detects python via python3/python/py -3
• Creates venv only if missing
• Activates using bin/activate (Linux/Mac) or Scripts/activate (Windows)
• Upgrades pip
• Installs requirements.txt if present
• Shows clear status messages

Tested on Windows (Git Bash).

[!NOTE] Introduces a cross-platform scripts/dev_setup.sh that creates/activates a Python venv, upgrades pip, and installs requirements.txt if present.

• Scripts:
  • New scripts/dev_setup.sh:
    • Detects Python command (python3/python/py -3).
    • Creates venv in .venv if missing and activates it (Linux/Mac bin, Windows Scripts).
    • Upgrades pip and installs dependencies from requirements.txt when available.
    • Emits clear success/error messages.

Summary of Changes

Hello @devendra1973, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a significantly improved dev_setup.sh script designed to provide a more robust and cross-platform compatible developer environment setup. It automates the detection of Python, intelligent creation and activation of virtual environments, upgrading pip, and installing project dependencies, all while offering clear user feedback. This enhancement aims to simplify the initial setup experience for developers on both Windows (via Git Bash) and Unix-like systems.

Highlights

• Python Detection: The script now intelligently detects the Python executable by trying python3, python, and py -3, ensuring broader compatibility across different systems.
• Virtual Environment Management: A virtual environment (.venv) is now created only if it doesn't already exist, preventing unnecessary re-creation and speeding up subsequent runs.
• Cross-Platform Activation: The script dynamically activates the virtual environment using the correct path (bin/activate for Linux/Mac or Scripts/activate for Windows), improving cross-platform usability.
• Dependency Installation: Pip is automatically upgraded, and project dependencies are installed from requirements.txt if the file is present, streamlining project setup.
• User Feedback: Clear status messages are now displayed throughout the setup process, indicating success, failure, or informational notes to the user.
