using agent with `--provider openai` throws `TypeError: 'OpenAI' object is not callable`

To be fair I am getting the same error for openai and anthropic so maybe i'm doing something wrong here:

TypeError: 'OpenAI' object is not callable
```

## Step 2
- Making sure `ssage` works if not in agent mode

```sh
onyx@SRV-ONYX: ~ % ssage --provider openai --model "deepseek/deepseek-chat:free" --base_url "https://openrouter.ai/api/v1" --api_key "sk-or-v1-" --log "does this work without agent mode?"
Based on the error message from your previous attempt, it seems there's an issue with the OpenAI
provider configuration when using agent mode. Let's try without agent mode as you suggested:

ssage --provider openai --model "deepseek/deepseek-chat:free" \
--base_url "https://openrouter.ai/api/v1" \
--api_key "sk-or-v1-" \
"test query"

Important notes:

1 Remove the --mode agent flag as this was causing the TypeError
2 Verify your API key is still valid
3 Check your Python package versions if the error persists

If you still encounter issues, consider:

pip install --upgrade shell-sage cosette

Remember to keep your API key secure and never share it publicly. Consider using environment variables
for sensitive information.
```

## Step 3
- Testing if agent mode works with anthropic

## Step 4
- Testing if anthropic works without agent mode

```sh

^^^^^^^^^^^^^^^
AttributeError: 'OpenAI' object has no attribute 'messages'
onyx@SRV-ONYX: ~ %
```

## Step 5
- Checking `ssage` version

```sh
onyx@SRV-ONYX: ~ % ssage --version
usage: ssage [-h] [--v] [--pid PID] [--skip_system] [--history_lines HISTORY_LINES] [--mode MODE]
[--log] [--provider PROVIDER] [--model MODEL] [--base_url BASE_URL] [--api_key API_KEY]
[--code_theme CODE_THEME] [--code_lexer CODE_LEXER] [--verbosity VERBOSITY]
query [query ...]
ssage: error: the following arguments are required: query
onyx@SRV-ONYX: ~ % ssage --v
ssage 0.1.0
onyx@SRV-ONYX: ~ %
```

## Step 6
- Checking versions of dependencies

```sh
onyx@SRV-ONYX: ~ % which ssage
ssage: aliased to /home/onyx/code/ai/text/generation/sage/venv/bin/ssage
onyx@SRV-ONYX: ~ % code/ai/text/generation/sage/venv/bin/pip list

i have been using openai as a provider this whole time so maybe the config file conflicts?
also interesting that the model brought up cosette, wonder if there's something there.
wish we could use Word Wrap here in issues so you dont have to horizontal scroll to see the full command.

anyway, thats what im seeing on my end.

Start in shell_sage/core.py around main and get_res, then inspect the provider initialization and the call paths shown in cosette/toolloop.py and claudette/core.py. Reproduce the commands with the listed dependency versions and compare normal and agent modes. Done means both OpenAI and Anthropic providers run without the reported TypeError or AttributeError.
