Split the large `parser.rs` file into logical submodules within `front/parser/src/parser/` to improve code structure and maintainability. Changes: - **New Module Structure**: - `asm.rs`: `parse_asm_block` - `control.rs`: `parse_if`, `parse_while`, `parse_for` - `decl.rs`: `parse_variable_decl`, `parse_const`, `parse_let`, `parse_var` - `expr.rs`: `parse_function_call`, `parse_parentheses` - `functions.rs`: `parse_function`, `parse_parameters`, `extract_body` - `io.rs`: `parse_println`, `parse_print`, `parse_input` - `items.rs`: `parse_import`, `parse_proto`, `parse_struct` - `stmt.rs`: `parse_assignment`, `parse_block`, `parse_statement` - `types.rs`: Type parsing logic moved from `type_system.rs` (`parse_type`, `parse_type_from_token`, etc.) - `parse.rs`: Main `parse()` entry point and module declarations. - **Cleanup**: - Removed `type_system.rs` (logic moved to `types.rs`). - Updated `mod.rs` to expose the new structure. - Fixed imports across the crate to point to new module locations. - Resolved unused import warnings in `main.rs` and `runner.rs`. This refactoring decouples parser components, making it easier to navigate and extend individual language features. Signed-off-by: LunaStev <luna@lunastev.org>

This PR performs a major refactoring of the parsing logic by decomposing the monolithic
parser.rsand the auxiliarytype_system.rsinto a well-structured directory of specialized submodules. This change significantly improves the maintainability and navigability of the frontend logic.Key Changes
1. Parser Modularization
The parser has been split into the following submodules within
front/parser/src/parser/:asm.rs: Logic for parsing inline assembly blocks (asm { ... }).control.rs: Handles control flow structures includingif,while, andforloops.decl.rs: Consolidates variable and constant declarations (const,let,mut,var).expr.rs: Manages expression-related parsing such as function calls and grouped parentheses.functions.rs: Handles function definitions, parameter lists, and body extraction.io.rs: Logic for I/O statements includingprint,println, andinput.items.rs: Parsing for top-level items such asimport,proto, andstruct.stmt.rs: Generic statement handling, including assignments and block parsing ({ ... }).types.rs: Consolidated type parsing logic (moved from the now-deletedtype_system.rs).parse.rs: The primary entry point containing the mainparse()function.2. Cleanup & Integration
front/parser/src/parser/type_system.rsand integrated its logic intoparser/types.rsto keep type-related parsing logic in one place.mod.rsto export the new module structure and refactored imports across thewaveccrate (specifically inmain.rsandrunner.rs) to resolve warnings and ensure compatibility with the new structure.Impact
parser.rs.
