test: add full cross-language IR test suite
Add comprehensive integration test matrix covering: 1. 30+ same-language test cases for C/C++/Go/Rust/Zig/Python/Java/C# 2. 20+ cross-language FFI/mixed-language scenarios 3. New test runner script for automated validation 4. Build system integration for new test target Update pipeline runner to improve cross-language symbol detection accuracy for all supported language
