Anthony Shaw c65e8ab0b5 Fix Python cookbook recipes to use correct async SDK API
All 5 Python recipes and their markdown docs used a synchronous,
kwargs-based API that doesn't match the real github-copilot-sdk:

- client.start() -> await client.start() (all methods are async)
- create_session(model=...) -> create_session(SessionConfig(model=...))
- session.send(prompt=...) -> session.send(MessageOptions(prompt=...))
- session.wait_for_idle() -> session.send_and_wait() (wait_for_idle doesn't exist)
- event['type']/event['data']['content'] -> event.type/event.data.content
- All code wrapped in async def main() + asyncio.run(main())

Verified all imports resolve against github-copilot-sdk.

# Error Handling Patterns
Handle errors gracefully in your Copilot SDK applications.
> **Runnable example:** [recipe/error_handling.py](recipe/error_handling.py)
>
> ```bash
> cd recipe && pip install -r requirements.txt
> python error_handling.py
> ```
## Example scenario
You need to handle various error conditions like connection failures, timeouts, and invalid responses.
## Basic try-except
```python
import asyncio
from copilot import CopilotClient, SessionConfig, MessageOptions
async def main():
client = CopilotClient()
try:
await client.start()
session = await client.create_session(SessionConfig(model="gpt-5"))
response = await session.send_and_wait(MessageOptions(prompt="Hello!"))
if response:
print(response.data.content)
await session.destroy()
except Exception as e:
print(f"Error: {e}")
finally:
await client.stop()
if __name__ == "__main__":
asyncio.run(main())
```
## Handling specific error types
```python
try:
await client.start()
except FileNotFoundError:
print("Copilot CLI not found. Please install it first.")
except ConnectionError:
print("Could not connect to Copilot CLI server.")
except Exception as e:
print(f"Unexpected error: {e}")
```
## Timeout handling
```python
session = await client.create_session(SessionConfig(model="gpt-5"))
try:
# send_and_wait accepts an optional timeout in seconds
response = await session.send_and_wait(
MessageOptions(prompt="Complex question..."),
timeout=30.0
)
print("Response received")
except TimeoutError:
print("Request timed out")
```
## Aborting a request
```python
session = await client.create_session(SessionConfig(model="gpt-5"))
# Start a request (non-blocking send)
await session.send(MessageOptions(prompt="Write a very long story..."))
# Abort it after some condition
await asyncio.sleep(5)
await session.abort()
print("Request aborted")
```
## Graceful shutdown
```python
import signal
import sys
def signal_handler(sig, frame):
print("\nShutting down...")
try:
loop = asyncio.get_running_loop()
loop.create_task(client.stop())
except RuntimeError:
asyncio.run(client.stop())
sys.exit(0)
signal.signal(signal.SIGINT, signal_handler)
```
## Best practices
1. **Always clean up**: Use try-finally to ensure `await client.stop()` is called
2. **Handle connection errors**: The CLI might not be installed or running
3. **Set appropriate timeouts**: Use the `timeout` parameter on `send_and_wait()`
4. **Log errors**: Capture error details for debugging
