cargo-mutants 24.4.0!

[sourcefrog]

• Changed: Baselines and mutants are now built with cargo test --no-run rather than cargo build --tests as previously. This avoids wasted build effort if the dev and test Cargo profiles are not the same, and may better distinguish build failures from test failures. With --test-tool=nextest, the corresponding cargo nextest run --no-run is used.

• Fixed: .ignore files can no longer affect source tree copying, so test files listed in a .ignore (e.g. *.snap for Insta snapshots) are now correctly copied into temporary build directories.

• Fixed: Don't visit files marked with #![cfg(test)] (or other inner attributes that generally cause code to be skipped.)

• Fixed: Paths to module files nested within mod blocks are now correctly resolved.

• Added: Document stability policy in the manual.

• New: Generate mutations that delete the ! and - unary operators.
