Description

Make the README a concise introduction and community entry point, while keeping setup instructions and detailed guides on the website.

• Explain the scanner, CoPyRIT GUI, and Python framework, with direct links to their website guides.
• Put community participation and contribution opportunities in the opening, with automatically updated contributor, merged-PR, and closed-issue badges directly below the title.
• Highlight Discord and the whitepaper, and separate research/citation information from trademark notices.
• List supported model providers and link to provider setup, optional LiteLLM integrations, and HTTP, WebSocket, Playwright, and custom targets.

Only README.md changes. The website FAQ is separate work and is not included here.

Tests and Documentation

• git diff --check origin/main...HEAD: passed.
• Commit-time pre-commit hooks: passed for applicable hooks; code/notebook-specific checks were skipped where no files matched.
• Checked the actual GitHub Markdown rendering and verified the badge endpoints and linked website guides.
• Unit tests, documentation builds, and JupyText execution were not run because this is a root-README-only change with no executable examples or website-source changes.
