chore: remove all outdated v2 assets, screenshots, docs, and temp files

[mrNLK]

Summary

The repo has accumulated a lot of outdated v2-era files — old HTML pages, duplicate screenshots, stale docs, temp artifacts, and branding leftovers. The current version is live at https://sourcekit-docs.netlify.app/ (the "Deep Blue" theme). Everything not aligned with that should go.
