This commit introduces the foundational structure for the parser and
Abstract Syntax Tree (AST). It includes a new `Parser.hpp` header that
outlines the primary parsing functions for top-level declarations like
`modules`, `structs`, `enums`, and `functions`. It also adds a
`toString` function for the AST to aid in debugging and visualization.
The commit also updates the `Expected.hpp` utility by adding new error
codes like `ecUnexpectedToken`, `ecExpectedSemicolon`,
`ecImportInsideModule`, and `ecUnimplemented` to provide more granular
and descriptive parsing errors. The `Tokenizer` has been updated to use
these new, more specific exceptions.

This commit refactors several AST nodes to use `Optional<T>` for fields
that are not always present. This includes `attribute` in
`ReflectionExpression`, `elseBranch` in `IfStatement` and
`WhileStatement`, `defaultCase` in `MatchStatement` and
`SwitchStatement`, and `preLoop` and `postLoop` in `CForStatement`. This
change improves the robustness and clarity of the AST by explicitly
modeling optionality.

This commit adds `Uninitialized` to several enums in `Common.hpp` to
ensure they are properly initialized.
It also adds missing binary operators like `BitAnd`, `BitXor`,
`Adition`, and `Multiplication`. This change improves the robustness and
functionality of the AST parser.

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- **Namespace Change**: The `node` namespace has been replaced by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.

Introduces the comprehensive header file for the Abstract Syntax Tree,
providing the foundational structures for the parser and subsequent
compiler stages.
This initial version defines all node types required to represent the
language's grammar, including:
- Top-level program structure and module declarations.
- All statement types, including control flow, loops, and deferrals.
- A semantic expression tree designed for a Pratt parser (Unary, Binary,
Function Calls, etc.).
- A robust, recursive type system for handling complex type signatures.
The design employs modern C++ for safety and clarity:
- `std::unique_ptr` establishes clear ownership of child nodes.
- `std::variant` provides type-safe polymorphism for Statement,
Expression, and Declaration nodes.
- `std::optional` is used to accurately model optional grammar rules.
- `SourceLocation` is included in every node to support detailed error
reporting.
