Add Resume Generator from User Input (Text or Documents)

Develop a resume generation feature that creates a professional resume from user-provided input.

* Accept both **text-based input** (e.g., user describes experience, skills, and education) and **document uploads** (e.g., existing resumes, certificates, or job descriptions).
* Parse and structure the information into standard resume sections (summary, work experience, education, skills, achievements).
* Offer multiple output formats (PDF, DOCX, Markdown).
* Ensure data cleaning and consistency in formatting and tone across generated resumes.

note: divide into sub-tasks please!
