Improve CONTRIBUTING.md for Clarity, Onboarding & Architectural Rigor

[Jaidhuria]

🔍 Problem Statement

The existing CONTRIBUTING.md for SpectraGraph is philosophically strong and technically accurate, but it places a high cognitive load on new contributors.
First-time contributors—especially those unfamiliar with strict, multi-service, ethics-driven architectures—may struggle to quickly understand where changes belong, what rules are non-negotiable, and how to submit a reviewable PR.

🎯 Objectives

This PR refines the contributing documentation to:

Reduce onboarding friction for new contributors

Improve scannability and navigation through clearer structure and hierarchy

Explicitly separate rules, requirements, and guidance

Reinforce SpectraGraph’s production-grade, security-conscious, and ethics-first stance

Align the documentation with standards seen in mature OSINT / security-focused open-source projects

🛠️ Solution

This update restructures and clarifies CONTRIBUTING.md without changing project policy or philosophy:

Introduces a clear narrative flow: philosophy → architecture → rules → setup → contribution paths

Makes architectural boundaries and dependency rules explicit and non-ambiguous

Adds strong visual hierarchy (sections, warnings, checklists) for faster scanning

Clearly documents where specific types of changes must live

Reinforces ethical and security expectations with explicit “do not” guidance

Improves contributor confidence by setting clear expectations for PR quality and review criteria

✅ Impact

Faster onboarding for new contributors

Fewer mis-scoped PRs and architectural violations

Clearer expectations for reviews and approvals

Stronger signal that SpectraGraph is a serious, production-grade OSINT platform

🧪 Scope & Risk

Documentation-only change

No code, behavior, or policy changes

No backward compatibility concerns
