chore: simplify docs for LLM automation, remove platform-specific install steps

- Rewrite README.md to focus on LLM-driven install setup
- Simplify QUICKSTART.md to minimal LLM instruction guide
- Rewrite CONFIG.md to remove platform-specific path examples
- Delete platform-specific IDE docs (CLAUDE.md, CURSOR.md, VSCODE.md, WINDSURF.md)
- Simplify REMOTE_AGENTS.md to remove Wine install details
- Clean up TROUBLESHOOTING.md to remove platform install sections
- Ignore .vscode/ and .codegraph/ directories
- Untrack server.json (should remain tracked - already restored)
