Function contains_dynamic_shell_syntax 

pub fn contains_dynamic_shell_syntax(command: &str) -> bool

Returns whether a shell command contains syntax whose meaning depends on shell expansion rather than the literal argument text.

Safety-sensitive classification must only operate on static command shapes. Parameter expansion, command substitution, brace expansion, globbing, and unquoted backslash escapes can otherwise turn a harmless-looking token into a different executable argument at runtime. Backslash escapes inside double-quoted arguments are consumed as literal argument syntax so patterns such as rg -n "\\[profile" remain classifiable.
