Add support for Vivado 2025.2 (202520)

[humdrum00001010]

Summary

• Add install config and hash for Vivado ML Standard 2025.2
• Fix configure_docker.sh to support newer settings-store.json format (Docker Desktop 4.x+) and raise minimum swap from 4 GiB to 8 GiB
• Add JAVA_TOOL_OPTIONS=-Xmx2g to prevent OOM kills during installation
• Fix validate_internet to use curl instead of ping (more reliable on macOS)

Test Plan

• Run setup.sh with Vivado 2025.2 installer binary
• Verify Docker swap is set correctly on fresh Docker Desktop install

Hey,
Does your de_start.sh script work? I didn't test it with your code but in my experience the folder structure changed with Version 2025 from Xilinx/Vivado/<VersionNr> to Xilinx/<VersionNr>/Vivado.

I picked this up and opened a follow-up PR with local 2025.2 validation and the remaining 2025 layout/runtime path fixes:

#82

I validated install, launch, vivado -version, and a minimal batch synth on Apple Silicon (macOS 26.4 / M1 Pro).
