Checks

Looks like test validation process is not established for this repo, I did following checks. If not enough, pleas let me know how to deal with additional checks and tests.

No Detection Case

After building, run the command with execution files in the target dir.
As expected no errors occurred.

% cargo build                                   
% ./target/xtask/debug/xtask dependencies unused
[2024-09-08T12:23:34Z INFO  tracel_xtask] Execution environment: std

cargo-machete didn't find any unused dependencies in .. Good job!
Done!

Detection Case

To detect unused packages, I added cfg-if for instances and executed the command.

% cargo add cfg-if                    
error: `cargo add` could not determine which package to modify. Use the `--package` option to specify a package. 
available packages: tracel-xtask, tracel-xtask-macros, xtask
toru@toru-mac xtask % cargo add cfg-if --package tracel-xtask

             - core
             - rustc-dep-of-std

After building, run the command with execution files in the target dir.
As expected an error occurred.

% cargo build   
% ./target/xtask/debug/xtask dependencies unused
[2024-09-08T12:24:21Z INFO  tracel_xtask] Execution environment: std
[2024-09-08T12:24:21Z INFO  tracel_xtask::commands::dependencies] Cargo: run unused dependencies checks
[2024-09-08T12:24:21Z INFO  tracel_xtask::utils::process] Command line: cargo machete
Analyzing dependencies of crates in this directory...
cargo-machete found the following unused dependencies in .:
tracel-xtask -- ./crates/tracel-xtask/Cargo.toml:
        cfg-if

If you believe cargo-machete has detected an unused dependency incorrectly,
you can add the dependency to the list of dependencies to ignore in the
`[package.metadata.cargo-machete]` section of the appropriate Cargo.toml.
For example:

[package.metadata.cargo-machete]
ignored = ["prost"]

You can also try running it with the `--with-metadata` flag for better accuracy,
though this may modify your Cargo.lock files.

Done!
Error: Unused dependencies found!

Conflicts is detected for Cargo.lock. It has changed due to my editor (VSCode) automatically, so it may be correct. If downgrade is necessary, I will do that with vim or something else.

Unnecessary, so delete them.
