1/// Applies the `.sig` variant to a list of patterns.
2///
3/// This function takes a list of patterns and appends the `.sig` variant to
4/// each pattern. If the pattern starts with `!`, the pattern is negated.
5///
6/// # Arguments
7/// * `patterns` - A vector of patterns to apply the `.sig` variant to.
8///
9/// # Returns
10/// A vector of patterns with the `.sig` variant applied.
11///
12/// # Examples
13///
14/// ```
15/// use soar_utils::pattern::apply_sig_variants;
16///
17/// let patterns = vec!["foo", "!bar", "baz"]
18///     .into_iter()
19///     .map(String::from)
20///     .collect();
21/// let sig_variants = apply_sig_variants(patterns);
22///
23/// assert_eq!(sig_variants, vec!["{foo,foo.sig}", "!{bar,bar.sig}", "{baz,baz.sig}"]);
24/// ```
