Bug: Inconsistent Output Paths in Functions

The copy_readme function uses a hardcoded output path, unlike process_files which respects the input_dir argument. This inconsistency causes the generated documentation and the index.mdx (README) to be written to different output directories when a custom input directory is provided.

The process_files function attempts to write MDX files to the mintlify subdirectory without ensuring the directory exists first. This can lead to a FileNotFoundError if the mintlify directory is missing when parser.process_file tries to write.
