This commit introduces `StaticType::Variadic` to represent variadic parameter types in function signatures. This allows for more precise type checking of functions that accept a variable number of arguments, such as arithmetic operators. Previously, variadic functions were handled using `StaticType::Any`, which was too permissive and could lead to runtime errors. The new `Variadic` type enforces that all arguments must conform to a specified inner type. Changes include: - Adding `StaticType::Variadic` to `src/ast/types.rs`. - Updating the type checker to handle `Variadic` types correctly when unifying with tuples or single arguments. - Modifying built-in functions like arithmetic operators to use `Variadic` for their parameter types. - Improving error messages for function call mismatches to be more specific. - Adding a new test case to ensure arithmetic type mismatches are caught at compile time. - A new example `data_stream_pipe_buffered.myc` is added. - The `HMA.myc` example now has a `Skip: output` directive.
