Thanks for the quick pace on the providers here: the Requesty and Fluxion entries made this one a straight copy of a pattern that already works.

Summary

Adds a runcrate provider to the standalone bughunter / brain.py LLM layer. Runcrate is an AI cloud with an OpenAI-compatible API (https://api.runcrate.ai/v1) that serves open models, so it plugs into the existing _chat_openai_compat path like the other gateways. It is opt-in: it is not in PROVIDER_PRIORITY, but a set RUNCRATE_API_KEY moves it to the front of auto-detect the way the other keyed providers do.

Type

• New feature / scanner module

Changes

• bughunter/brain.py: runcrate in DEFAULT_MODELS (Qwen/Qwen3-235B-A22B-Instruct-2507), PROVIDER_KEY_ENV, _init_provider (Bearer key from RUNCRATE_API_KEY, base https://api.runcrate.ai/v1), the OpenAI-compatible chat dispatch tuple, a short list_models starter list, and the module docstring.
• bughunter/engine.py: setup wizard option 12, --provider help and setup --provider choices, key maps for setup and providers (tier pay-as-you-go), saved-key loading, and the docs header.
• README.md provider table row and a CHANGELOG.md entry under Unreleased.
• tests/test_brain_auto_detect.py: five tests (key jumps to the front of auto-detect, init sets base URL and Bearer header and default model, no key stays unavailable, opt-in only, chat uses the OpenAI-compatible path).

Test Plan

• pytest tests/ passes locally: pytest -q gives 1158 passed (1153 on main before this change, plus the 5 new tests), Python 3.12.
• pytest tests/test_brain_auto_detect.py -q: 20 passed.
• No hardcoded targets, API keys, or real domain names
• Scanner additions use [CONFIRMED] / [POSSIBLE] / [INFORMATIONAL] confidence states (n/a, no scanner changes)
• New functionality has at least one regression test

The model ids in the default and starter list exist in GET https://api.runcrate.ai/v1/models today. I did not make a live chat call, so the request path is covered by the unit tests and the shared OpenAI-compatible code only.

Related Issue

None, this adds a provider.

Notes

Disclosure: I work on Runcrate.

This change was prepared with AI assistance (omp with Claude): the code, tests and this description were written with it, and the test commands above were run as part of preparing it.
