Fix Rust formatting (cargo fmt)

Apply automatic formatting via cargo fmt to:
- rust/src/tools/qwen.rs: Align comment indentation
- rust/tests/agent_tests.rs: Multi-line assert formatting
- rust/tests/claude_tests.rs: Multi-line assert formatting
- rust/tests/opencode_tests.rs: Multi-line assert formatting
