refactor(parser): Step 3 - Extract declarations module
- Create declarations module with box_definition, static_box, dependency_helpers - Move parse_box_declaration, parse_interface_box_declaration from mod.rs - Move parse_static_box and dependency checking logic - Temporarily restore parse_global_var, parse_function_declaration, parse_static_declaration to mod.rs - Fix visibility issues (pub vs pub(super)) - Fix TokenType::IMPLEMENTS not defined issue - Fix Loop AST node condition type mismatch - Build passes successfully Next: Step 4 - Extract items module for global_vars, functions, static_items
