ROOT CAUSE (Gemini consultation):
Technic blocks requests with old/deprecated build numbers. The hardcoded
'?build=1' was being rejected as an ancient launcher version.
SOLUTION:
- Fetch current stable launcher build from /launcher/version/stable4
- Use that build number in the modpack request
- Fallback to 999 if version check fails
This 'RV-Ready' approach requires zero maintenance as Technic updates
their launcher versions over time.
