Add a ydata-profiling comparison recipe

[JohnnyWilson16]

Summary

Document how fd.profile(df) differs from report-only profilers, with a small
side-by-side example.

Acceptance Criteria

• The page states that profiling tools describe data while freshdata can repair it.
• The example uses a tiny DataFrame and avoids large generated reports.
• The page links to docs/data-profiling.md.

From issue-backlog.md §5.

I can take issue #7. Plan: I’ll add a minimal side-by-side docs recipe that shows the same tiny DataFrame through d.profile(df) and ydata_profiling.ProfileReport (optional dependency) so contributors can quickly compare outputs. I’ll include: (1) a freshdata profiling + plan snippet, (2) a ydata-profiling snippet with package-install note, and (3) a short section on when to use freshdata vs ydata-profiling. I’ll also run mkdocs build --strict before opening a PR.

Status update: I am resuming this now after completing the architecture cross-link contribution. I confirmed the issue is still unassigned and there is no overlapping open PR. I will keep the original scope: one concise comparison recipe using the same small DataFrame, an optional-install note, practical guidance on when to use each tool, and a strict docs build.

Correction after tracing the current documentation history: this work was already completed by me in #14 and merged on 2026-06-17 (commit 27950b8). The merged docs/data-profiling.md section uses one tiny DataFrame for both tools, explains that profiling describes data while freshdata can proceed to a repair plan, keeps ydata-profiling optional, and is itself the acceptance-criteria target page. No follow-up PR is needed; maintainers can close this issue as completed. Sorry for the unnecessary resume note—I initially audited only open PRs and then verified the file history.

Verified on main (f295847): done in #14 (27950b8). docs/data-profiling.md has a "Compare with ydata-profiling" section. It runs both tools on one tiny DataFrame, explains that profiling describes the data while freshdata goes on to a repair plan, and keeps ydata-profiling as an optional install.
