Align docs/analysis files on one structure: metadata header, unnumbered
"مقدمه", numbered sections, and a final "نکات و پرسشهای باز" section.
- user-story.md: add "نیازمندیهای مرتبط" (FR refs) to each US, number
the sections, and update the last-updated date
- requirements-specification.md: define "گزارشدهنده" and align the
closing section name
- activity.md: add metadata header and مقدمه, drop English actor labels,
give each diagram an AD-NN id, and add a status line
- CONTRIBUTING.md: record the analysis docs standard as section ۷
- features/: Gherkin scenarios for US-01, US-05 and US-15
Added a comprehensive guide for contributing to the project, including steps for cloning the repository, creating a personal branch, committing changes, pushing to GitHub, and creating pull requests.
