This commit refactors the AST printing functionality by moving the
human-readable `toString` implementation into its own file
(`lib/src/Parser/AST/toString.cpp`) and introducing a new `toDot`
function in `lib/src/Parser/AST/toDot.cpp` for generating Graphviz DOT
format output.
The `AST.hpp` header is updated to declare both the new `toDot` function
and the modified `toString` function, which now uses an optional
`prefix` parameter for prettier tree output. The `Token.hpp`/`Token.cpp`
files are also adjusted to have `toString(const TokenV &)` return a
`std::string_view`, and `toString(const Token &)` provides a cleaner
string representation using only the token's value.

This commit introduces an utility factory function and structural
improvements to the Abstract Syntax Tree (AST).
* Adds a new `ASTNodePtr` C++20 concept to constrain template types to
be `std::unique_ptr`s pointing to AST nodes.
* Introduces a `MakeNode<T>()` factory function that uses this concept
to simplify and standardize the creation of new nodes.
* Fixed `NamespacedType` and added the missing `NamespacedIdentifier`
node.

This commit refactors the AST (Abstract Syntax Tree) to improve code
organization, clarity, and maintainability. The large single-file AST
definition has been split into multiple, logically grouped header files.
The key changes are:
- **New File Structure**: The single `Node.hpp` file is replaced by a
modular structure consisting of `Common.hpp`, `Declarations.hpp`,
`Expressions.hpp`, `Literals.hpp`, `Statements.hpp`, and a new central
`AST.hpp` header.
- **Improved Naming**: All AST node structs and their aliases have been
renamed to follow a consistent `[NodeName][NodeType]` convention, such
as `StructDeclaration` and `StructDeclNode`.
- **Namespace Change**: The `node` namespace has been replaced by
`arti::lang::ast::nodes` to provide better encapsulation and prevent
naming conflicts.
- **Type Aliases**: Helper aliases like `String`, `Vector`, and
`Variant` have been introduced to simplify the code.
