feat(providers): add AICraft OpenAI-compatible provider template

[BX166]

Summary

Adds AICraft (aicraftapi.com) as an OpenAI-compatible provider setup template, following the same descriptor-row pattern as SenseNova, Baseten, Groq, Cerebras, and Command Code.

• AICRAFT_TEMPLATE_ID = "aicraft"
• AICRAFT_BASE_URL = "https://aicraftapi.com/v1"
• AICRAFT_DEFAULT_MODEL = "claude-4.6-sonnet"
• AICRAFT_API_KEY_ENV = "AICRAFT_API_KEY"

Changes

• Four new consts plus one ProviderSetupApply::Compatible descriptor row, inserted before the unpublished agnes entry.
• Updated settings_value_names_fillable_then_unpublished to include aicraft in the fillable list.
• Added an aicraft entry to hosted_openai_compat_hosts_are_templates_not_enum_variants.
• Updated the module header comment.

Test plan

• The two touched unit tests (settings_value_names_fillable_then_unpublished, hosted_openai_compat_hosts_are_templates_not_enum_variants) are expected to pass under the existing crates/config test suite.

No-Issue: provider setup template addition; no tracking issue was filed for AICraft. (Line added by a maintainer to satisfy the required link check — the contribution itself is unchanged.)

Addressed the review: AICraft is now documented in docs/PROVIDERS.md alongside the other compatible templates. The new row sits between Command Code and Agnes:

| AICraft | compatible | ```https://aicraftapi.com/v1``` | ```claude-4.6-sonnet``` | ```AICRAFT_API_KEY``` |

This satisfies every_compatible_template_is_documented_for_operators (display name, base URL, and API key env are all present).

thank you! will work on getting this in

Thank you for this, @BX166 — and I'm sorry it took the route it did.

I'm closing it, but not because anything was wrong with the work. It followed
the descriptor-row pattern exactly, the tests were updated correctly, and you
came back and documented AICraft in docs/PROVIDERS.md when that was asked for.
The problem is the thing it plugs into.

We're removing provider setup templates entirely (#6289). The founder's call
today: these named hosts "were never supposed to" be special-cased, and should be
ordinary providers like every other OpenAI-compatible route. Codewhale already
has a full generic mechanism for that — [providers.<name>] with a base URL, a
model and a key env — so the template list was a compiled-in list of blessed
vendors that duplicated a capability users already had. Your PR is the eleventh
entry in a table that is about to stop existing, which is our architecture
problem, not your contribution's.

AICraft stays supported. I checked it out, and it's a real service — Hainan
AICraft Matrix Technology Co., Ltd., ICP 琼ICP备2026009730号-1, an aggregator
fronting DeepSeek, Qwen, GLM, MiniMax and Doubao. Nothing about it gave me
pause. Once #6289 lands, it works the same way every other compatible host does,
and I've carried your base URL and key env into that issue so the replacement
docs keep them.

One correction worth having on the record: the PR set the default model to
claude-4.6-sonnet, but AICraft doesn't advertise any Anthropic models — their
own site lists DeepSeek, Qwen, GLM, MiniMax and Doubao. I've noted on #6289 not
to carry that default across.

Two things that went wrong on our side, so you know none of it was you:

• Your CI never ran at all from Sept 14 until today. As a first-time
  contributor every workflow run parks at action_required until a maintainer
  approves it, and nobody had. That's a repo setting.
• The Lint failure was a six-line rustfmt wrap that we should have taken care
  of rather than sending back. I did fix it on our side.

If you want to keep contributing here — and I hope you do — #6289 itself is open,
and the replacement docs for compatible providers would be a natural place to
land AICraft properly.
