PR Summary

Low Risk
Documentation-only edits to README.md (formatting, links, and attribution) with no runtime or configuration changes.

Overview
Simplifies README.md by removing the centered HTML header/badges and embedded demo GIFs, leaving a cleaner Markdown-first intro and quickstart.

Updates self-hosting instructions and formatting (e.g., linkifying localhost, cleaning up numbered steps/table spacing, fixing a malformed .env.example link, and converting the Copilot URL to Markdown).

Expands the Tech Stack section to credit Streamdown, TanStack Query, and isolated-vm.

Greptile Summary

This documentation-only PR adds three tech stack entries to the README: Streamdown for streaming markdown, TanStack Query alongside Zustand for state management, and isolated-vm for isolated code execution. The additions accurately reflect libraries already in use in the codebase.

Confidence Score: 5/5

Safe to merge — documentation-only change with accurate additions.

All three added entries accurately reflect libraries used in the codebase (React Query is extensively documented in CLAUDE.md, isolated-vm is used for sandboxed execution, and Streamdown for streaming markdown). No code logic is affected.

No files require special attention.
