Honest link acquisition: awesome lists and communities

[eaitbrahim]

docs/seo/IMPLEMENTATION-ROADMAP.md Phase 2. Targets that are relevant and honest:

• PR to awesome-islamic-finance (project fits; disclose authorship — the brand is honesty)
• Ensure engine repo has useful GitHub topics (halal-finance, shariah, crypto) for topic-page discoverability
• Where the project is genuinely useful in Islamic-finance communities (r/IslamicFinance etc.), participate as a project author with disclosure — no astroturfing
• KPI: 5 referring domains by month 3, 15 by month 6 (docs/seo/SEO-STRATEGY.md §6)
