Introduces the `#use` preprocessor directive, allowing Myc scripts to explicitly declare dependencies on other Myc libraries. This change moves dependency management from a command-line argument to an in-script declaration, ensuring scripts are self-contained and can correctly resolve macros and other symbols. Key features include: - Declarations at the beginning of a file, evaluated before parsing. - Support for relative paths and a new `->` separator. - Automatic resolution of dependencies from specified search paths. - Idempotent loading to prevent duplicate parsing and evaluation. - No AST pollution; dependency management is a compile-time concern. The compiler's lexer has been updated to recognize `#` as a comment character, and the environment now manages search paths and loaded modules. This lays the groundwork for more complex library structures and improved code organization.
