Restructure 02-agents/providers/ into per-provider subfolders

Reorganize providers to match Python's providers/ structure where samples
are grouped by provider (anthropic/, azure/, openai/, foundry/, etc.)
instead of flat Agent_With_* directories.

- Create provider subfolders: a2a, anthropic, azure, custom, foundry,
  github-copilot, google-gemini, ollama, onnx, openai
- Move Agent_With_* projects into respective provider subfolders
- Merge standalone anthropic/, openai/, foundry/ folders into providers/
- Fix ProjectReference paths (depth increased by 1)
- Update slnx, AGENTS.md, README.md files
