docs(readme): add explicit integrations table for all 16 AI tools + expand sections

- Add 'AI Coding Tools & IDEs' table under Integrations listing every
  tool from the visual grid with connection type and setup note:
  Claude Code, Cursor, Windsurf, Claude Desktop, VS Code, GitHub
  Copilot, Cline, Roo Code, Continue, Goose, Kilo Code, Aider,
  Amazon Q, Zed, Claude SDK, REST API (109 endpoints)
- Add Neo4j to Graph Databases list (was in modules but missing here)
- Add Email and Repository ingestors to Data Sources
- Expand LLM Providers: add Groq, HuggingFace, Ollama entries
