Pull request overview

This PR extends compio-macros’s #[compio::main] / #[compio::test] attribute macros to accept runtime builder parameters and a nested with_proactor(...) configuration, and updates a couple of integration tests to use the new attribute-based configuration instead of manually building a runtime.

Changes:

• Reworks the #[compio::test] macro implementation to share logic with #[compio::main] and emit a runtime builder chain.
• Adds parsing/codegen for runtime builder params (name = value) and proactor builder params via with_proactor(name = value, ...).
• Updates compio crate tests to configure the proactor via macro parameters.
