🔧 Key Fixes

SLgMessageFactoryImpl Fix

// Problem: Interface doesn't declare throws InternalException
// Solution: Wrap in RuntimeException

public ProvideLocationRequest createProvideLocationRequest() {
    try {
        return (ProvideLocationRequest) createSlgMessage(...);
    } catch (InternalException e) {
        throw new IllegalStateException(
            "Failed to create Provide-Location-Request", e);
    }
}

SupportedFeaturesAvpImpl Import Fix

// Fixed imports in:
// - ProvideLocationRequestImpl.java
// - ProvideLocationAnswerImpl.java
// - LocationRequestImpl.java
// - LocationAnswerImpl.java

// Changed from:
// import static ...SLgAvpCodes.SupportedFeaturesAvpImpl;

// To:
// import ...SupportedFeaturesAvpImpl;

_3GPP_VENDOR_ID Constant

// Added constant instead of importing from removed class
private static final long _3GPP_VENDOR_ID = 10415L;
