Add a trust and safety section to the website

[Muawiya-contact]

Goal

Add a short trust/safety section to the website.

New users should quickly understand Diskern's safety model before downloading.

Suggested content

The section could explain:

- Scans are read-only.
- Nothing is deleted without review.
- Quarantine is reversible.
- Safety verdicts come from auditable rules, not AI guesses.

Site components live in:

site/src/components
site/src/pages/Home.jsx

Acceptance criteria

• Adds a concise trust/safety section to the homepage.
• Uses plain language.
• Looks good in light and dark theme.
• Site tests/build pass.
