Signed-off-by: erick-alcachofa <erick@artichoke.dev> 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.
