v5.4.8 — Python Dependencies & Java Improvements

What's New in v5.4.8

Python Dependency Management (PR #15)

• EthPillar now automatically creates and manages its own Python virtual environment (.venv)
• Required packages (requests, tqdm, console-menu, python-dotenv) are installed automatically

Java Support Improvements (PR #16)

• Added proper JDK version detection before upgrading Besu and Teku
• Safety checks now run before replacing the client binary
• Besu 26.6.0+ (which requires JDK 25) is now handled correctly

Thanks to @b0a7 (PR #15) and @rggjan (PR #16) for these improvements!
