* feat(wizard): add Opper as an LLM provider
Opper (https://opper.ai) is an EU-hosted AI gateway: 700+ models from
50+ providers behind one OpenAI-compatible API and one key. This adds it
to the setup wizard's LLM_PROVIDERS next to OpenRouter, with the same
shape: langchain_openai:ChatOpenAI pointed at
https://api.opper.ai/v3/compat, env var OPPER_API_KEY.
Models use Opper's bare model ids: claude-sonnet-4-6 (default), gpt-5.5,
gemini-3.8-flash and gpt-5.4-mini. Because the GPT ids are bare,
langchain-openai drops the 0.7 temperature for them the same way it does
for direct OpenAI gpt-5 models.
Checked: python -m py_compile scripts/wizard/providers.py, and each
model id against Opper's public model list
(GET https://api.opper.ai/v3/models). Not run locally: make lint and
make test.
Disclosure: Opper is my startup.

* docs: add Opper to the config example and READMEs
Add an Opper model example next to the other OpenAI-compatible
gateways, as requested in review:
- config.example.yaml: commented opper-claude-sonnet-4-6 block after
the other gateway examples (ChatOpenAI + base_url, OPPER_API_KEY)
- README.md and the translated READMEs: the same entry in the manual
model configuration examples, after OpenRouter
- .env.example and backend/docs/CONFIGURATION.md: OPPER_API_KEY, in the
shape of the Novita lines
claude-sonnet-4-6 is a pooled id in Opper's public catalogue
(GET https://api.opper.ai/v3/models). config.example.yaml still parses
with yaml.safe_load; config_version is unchanged because the schema is.
Disclosure: Opper is my startup.
