.NET: Python: Add AGENTS.md files and update coding standards (#3644)

* Add AGENTS.md files and update coding standards for Python

- Add root python/AGENTS.md with project structure and package links
- Add AGENTS.md for each package describing purpose and main classes
- Update .github/copilot-instructions.md with improved structure
- Update python/CODING_STANDARD.md with API review guidance:
  - Future annotations convention (#3578)
  - TypeVar naming convention (#3594)
  - Mapping vs MutableMapping (#3577)
  - Avoid shadowing built-ins (#3583)
  - Explicit exports (#3605)
  - Exception documentation guidelines (#3410)
- Simplify python/.github/instructions/python.instructions.md to reference AGENTS.md
- Remove AGENTS.md from .gitignore

* Fix purview import path in AGENTS.md

* Address PR review comments and restructure instructions

- Slim down .github/copilot-instructions.md to reference language-specific docs
- Add ADR section explaining templates and purpose
- Create dotnet/AGENTS.md with .NET-specific build commands, conventions, and sample guidance
- Update Python build/test instructions for core vs isolated changes
- Fix Microsoft.Extensions.AI package references
- Update kwargs guidance per issue #3642
- Fix Python sample helper placement (top, not bottom)
- Document new 'typing' poe task in DEV_SETUP.md

* Add 'typing' poe task to run both pyright and mypy

* Add kwargs guidelines from issue #3642 to CODING_STANDARD.md

* Clarify that connector packages pull in core as dependency

# AGENTS.md
Instructions for AI coding agents working in the Python codebase.
**Key Documentation:**
- [DEV_SETUP.md](DEV_SETUP.md) - Development environment setup and available poe tasks
- [CODING_STANDARD.md](CODING_STANDARD.md) - Coding standards, docstring format, and performance guidelines
## Maintaining Documentation
When making changes to a package, check if the package's `AGENTS.md` file needs updates. This includes:
- Adding/removing/renaming public classes or functions
- Changing the package's purpose or architecture
- Modifying import paths or usage patterns
## Quick Reference
Run `uv run poe` from the `python/` directory to see available commands. See [DEV_SETUP.md](DEV_SETUP.md) for detailed usage.
## Project Structure
```

└── tests/ # Integration tests
```
### Package Relationships
- `agent-framework-core` contains core abstractions and OpenAI/Azure OpenAI built-in
- Provider packages (`azure-ai`, `anthropic`, etc.) extend core with specific integrations
- Core uses lazy loading via `__getattr__` in provider folders (e.g., `agent_framework/azure/`)
### Import Patterns
```python
# Core imports
from agent_framework import ChatAgent, ChatMessage, tool
# Provider imports (lazy-loaded)
from agent_framework.openai import OpenAIChatClient
from agent_framework.azure import AzureOpenAIChatClient, AzureAIAgentClient
```
## Key Conventions
- **Copyright**: `# Copyright (c) Microsoft. All rights reserved.` at top of all `.py` files
- **Types**: Always specify return types and parameter types; use `Type | None` not `Optional`
- **Logging**: `from agent_framework import get_logger` (never `import logging`)
- **Docstrings**: Google-style for public APIs
- **Tests**: Do not use `@pytest.mark.asyncio` (auto mode enabled); run only related tests, not the entire suite
- **Line length**: 120 characters
- **Comments**: Avoid excessive comments; prefer clear code
- **Formatting**: Format only files you changed, not the entire codebase
## Sample Structure
1. Copyright header: `# Copyright (c) Microsoft. All rights reserved.`
2. Required imports
3. Module docstring: `"""This sample demonstrates..."""`
4. Helper functions
5. Main function(s) demonstrating functionality
6. Entry point: `if __name__ == "__main__": asyncio.run(main())`
When modifying samples, update associated README files in the same or parent folders.
