Note: The increase in ignored tests is not due to any additional ignores added in OE.
These are primarily upstream-defined ignores introduced in Rust 1.92.0, likely due to
architecture-specific constraints or target configuration differences. The only OE-side
ignore added is for the no_std simple-runs test on 32-bit ARM, limited to a known upstream
issue (rust-lang/rust#146996) and can be reverted once the issue is resolved.
