fix(input): return a bool|string|string[]|null enum from get_option

`InputInterface::get_option` returned `PhpMixed`, so the negation branch
of `Input::get_option` reproduced PHP's `return !$value;` as
`!value.as_bool().unwrap_or(false)`, which inverts the result for a
string value instead of leaving it `false`. It now returns
`InputOptionValue`, whose `to_bool` is PHP's truthiness cast.

The narrowing also removes the `Vec<PhpMixed>` element handling the
commands carried for array options: `as_array` hands back `&[String]`,
so the `filter_map(|v| v.as_string())` chains at eight call sites
collapse. Its other accessors keep `PhpMixed`'s names and meanings
(`is_null`, `as_bool`, `as_string`, `to_bool`), and
`From<InputOptionValue> for PhpMixed` covers the callers that feed the
value back into an `IndexMap<String, PhpMixed>` or a `PhpMixed`
parameter.

`Input` keeps its parsed options and `InputOption` its defaults as
`PhpMixed`, so `Input::get_option` is where the narrowing happens and
where a value outside the domain panics.
