Contributions summary:Filip primarily focused on improving the testing framework and ensuring the reliability of the rustup toolchain installer. Their contributions included writing new tests, specifically targeting scenarios with no default toolchain and the correct handling of stray hash files during toolchain installations. They also implemented improvements to the testing utilities, such as adding the `expect_not_stderr_ok` function. The work involved modifying existing tests and the test setup to make them less brittle.
