Fix VerifyError in rebuilt APKs by enforcing consistent API level limits during decode/build

[Copilot]

APKs with API level > 29 fail verification after rebuild with errors like VerifyError: register v4 has type BooleanConstant but expected Reference: java.lang.String. Root cause: baksmali disassembles using original API level (e.g., 34) while smali reassembles limited to API 29, creating opcode incompatibilities.

Changes

• Added SmaliConstants.MAX_SUPPORTED_API_LEVEL: Centralizes the API 29 limit referenced by issue [BUG] dex version changed after compilation. iBotPeaches/Apktool#3641
• Modified SmaliDecoder.decode(): Applies API level limit during disassembly by detecting original API level, capping at 29, and reloading the dex container with limited opcodes
• Updated SmaliBuilder: Uses shared constant instead of hardcoded value

// Before: baksmali uses API 34, smali uses API 29 → verification errors
DexFileFactory.loadDexContainer(mApkFile, null);  // Uses original opcodes

// After: both use API 29 → consistent bytecode
int limitedApiLevel = Math.min(originalApiLevel, SmaliConstants.MAX_SUPPORTED_API_LEVEL);
DexFileFactory.loadDexContainer(mApkFile, Opcodes.forApi(limitedApiLevel));

This ensures baksmali and smali operate at the same API level, eliminating verification failures in rebuilt APKs.
