Replace hardcoded validator class lists with a declarative #[Mixin]
attribute and extract the mixin generation logic into a reusable
CodeGen namespace under src-dev/CodeGen/.
The new MixinGenerator discovers prefix definitions and filtering
rules by scanning #[Mixin] attributes on the target namespace's
classes, removing the need for hardcoded configuration. It supports
configurable interface types (Builder for __callStatic, Chain for
__call) with custom suffixes, return types, and root extends.
This is the first step toward extracting the code generation into a
standalone package that can map __call/__callStatic to any namespace,
possibly for Respect/StringFormatter and any kind of project in the
future.
This is a mid-size refactor that affects several validators.
Most prominently, the ones that had an `$identical` parameter
to deal with case sensitiveness.
This parameter was confusing, effectively making validators such
as `Contains` behave very differently for arrays versus strings.
In arrays, `$identical` meant "the same type", while it in strings
it meant "case sensitive".
That parameter was removed, and the default behavior is now to
always compare **case sensitive** and strict typing.
A document explaining how to combine other validators in order
to achieve case _insensitive_ comparisons was added.
Additionally, the `Call` validator was refactored back to be
suitable to take on the task of being a fast, quick composable
validator.
With the introduction of `Circuit`, we can shift the responsibility
of dealing with possible mismatches to the user. This kind of type
handling is demonstrated in how I refactored `Tld` to account for
the type mismatch without setting error handlers.
We've always considered renaming this directory, as it's not a common
standard to name `library` the directory where the source code of a
library it. Having it as `src/` is a common pattern we find in several
PHP libraries these days.
