+/// Confirmer setup for managing confirmation state
+///
+/// This Setup manages the confirmation flag within the program's resource
+/// store. It registers a [`Confirmer`] resource and sets up a hook that
+/// checks the user's confirmation mode during program execution.
+///
+/// # Usage
+///
+/// This Setup can be registered using the
+/// [`Program`](https://docs.rs/mingling/latest/mingling/struct.Program.html)
+/// `with_setup` method, for example:
+///
+/// ```rust
+/// # use mingling::MockProgramCollect as ThisProgram;
+/// use mingling::Program;
+/// use mingling::setup::ConfirmerSetup;
+///
+/// let mut program = Program::<ThisProgram>::new();
+/// program.with_setup(ConfirmerSetup);
+/// ```
+///
+/// # Behavior
+///
+/// - Registers a [`Confirmer`] resource that tracks confirmation state.
+/// - At the beginning of command execution, checks whether the user's
+///   confirmation mode is set to `Skip`.
+/// - If confirmation is skipped, the [`Confirmer`] resource is updated
+///   to record the confirmed state.
+///
+/// # Notes
+///
+/// - This Setup applies uniformly to all subcommands of the entire program.
+/// - The confirmation state is determined by the global `config` setting;
+///   it does not support per-command overrides.

+/// Uses the standard input as arguments for the program
+///
+/// This Setup can take standard input supplied via a pipe or redirect,
+/// split it according to whitespace and quoting rules, and append
+/// the resulting arguments to the end of the command argument list.
+///
+/// # Usage
+///
+/// This Setup can be registered using the
+/// [`Program`](https://docs.rs/mingling/latest/mingling/struct.Program.html)
+/// `with_setup` method, for example:
+///
+/// ```rust
+/// # use mingling::MockProgramCollect as ThisProgram;
+/// use mingling::Program;
+/// use mingling::setup::StandardInputArgsSetup;
+///
+/// let mut program = Program::<ThisProgram>::new();
+/// program.with_setup(StandardInputArgsSetup);
+/// ```
+///
+/// # Behavior
+///
+/// - Standard input is only read when it is not a terminal (i.e., when
+///   there is piped or redirected input).
+/// - The read content is split into multiple arguments according to
+///   whitespace and quoting rules.
+/// - If the standard input content is empty, no arguments are produced.
+/// - All input is converted to UTF-8 encoding (lossy conversion is used
+///   when strict parsing is not possible).
+///
+/// # Notes
+///
+/// - This Setup applies uniformly to all subcommands of the entire program
+///   and does not provide fine-grained control. If you need different
+///   standard input behavior across different subcommands (e.g., some
+///   subcommands read stdin while others ignore it), **do not use this Setup**.
+/// - This Setup does **not** provide any validation rules. Content provided
+///   via standard input is treated as trusted arguments and appended directly.
+///   As a result, the input source can also inject arbitrary arguments into
+///   the command, so you should be careful when processing untrusted input.
