Add project logo and branding assets to repo

[zeweihan]

Add official branding assets to the repo so contributors can use them: Logo SVG and PNG, icon variants, social media banner, brand guidelines.

Test the SVG variants against dark-mode terminal themes before committing them. Many OSINT researchers run CLI environments where transparent backgrounds cause hardcoded black paths to vanish entirely. I see this often when tools get integrated into custom workbenches. Leaving path fills dynamic solves it. Alternatively, adding a high-contrast, white-bordered fallback to the asset folder prevents the logos from disappearing on dark terminals. How do these render on your current local test runner?

Hey @sophymarine 👋

Great point on dark-mode terminal rendering. You're right — hardcoded black paths are a real issue for CLI-heavy workflows.

We'll make sure to:

1. Use dynamic currentColor or currentColor-based path fills where possible
2. Include a high-contrast white-bordered fallback variant in the assets folder
3. Test against common dark terminal themes (iTerm2, Warp, Windows Terminal)

Appreciate the heads-up — this is exactly the kind of edge case that's easy to miss early on. 🙏
