description	Add and maintain Sounio tests: `tests/run-pass`, `tests/compile-fail`, `tests/ui`, and Rust integration tests under `compiler/tests`; use when writing regressions or adjusting diagnostics expectations.

Sounio Tests Suite

Overview

Write minimal, high-signal tests that protect language semantics, diagnostics, and regressions.

Workflow

1) Choose the right test bucket

• tests/run-pass/: should compile and run
• tests/compile-fail/: should fail to compile
• tests/ui/: diagnostics/error message matching via //@ error-pattern:
• compiler/tests/: Rust integration tests for compiler subsystems

2) Keep tests small and explicit

• Avoid relying on features listed as missing in compiler/docs/KNOWN_LIMITATIONS.md.
• Prefer one behavior per test file; add //@ ignore if it’s documenting an aspirational feature.

3) Run the narrowest validation first

• If you changed Rust compiler code: cd compiler && cargo test <name>
• If you changed language behavior: run the smallest relevant test subset first
