fix: Update Compiler class to use object type for context parameter

The Compiler class in compiler.ts has been updated to use the object type for the context parameter in the compile method. This ensures that the context parameter is always an object, even if it is not provided or is not of type object. This change improves the type safety and reliability of the code.
