feat(models): add InclusionAI Ling-3.0-flash

[vicovaro]

Summary

Adds InclusionAI Ling-3.0-flash, a 124B-parameter native hybrid-reasoning MoE (5.1B active) model, with mappings on DeepInfra and NovitaAI.

References:

• https://deepinfra.com/inclusionAI/Ling-3.0-flash
• https://novita.ai/models/model-detail/inclusionai-ling-3.0-flash

What changed

• packages/models/src/models/inclusionai.ts (new): ling-3.0-flash model definition with DeepInfra + NovitaAI mappings.
• packages/models/src/models.ts: registers the new model and the chatTemplateThinkingKey mapping field.
• packages/actions/src/prepare-request-body.ts: the default OpenAI-compat request path now handles chatTemplateThinkingKey — reasoning_effort: "none" maps to chat_template_kwargs: { enable_thinking: false }, any other effort maps to { enable_thinking: true }.
• packages/actions/src/prepare-request-body.spec.ts: unit tests for the Ling thinking translation on both providers.

Pricing note

The DeepInfra rates ($0.045/M in, $0.10/M out, $0.008/M cached) are a promotional sale — not the standard list price. Noted in a comment on the DeepInfra mapping so the sale is called out; the rates will need updating when the promo ends.

Reasoning handling

Ling-3.0-flash is a hybrid reasoning model that thinks by default (per its HF card / vLLM chat template). Its only reasoning control is the chat-template flag enable_thinking — it has no native reasoning_effort tiers. So:

• Both mappings declare reasoning: true, reasoningEfforts: ["none"], and chatTemplateThinkingKey: "enable_thinking".
• supportedParameters excludes reasoning_effort so it is never forwarded to the provider (matching the DeepSeek V3.2-on-Novita precedent).

Verification

• pnpm build — full workspace build passes (17/17).
• Unit tests for packages/models and packages/actions pass (401 tests, incl. 6 new Ling tests).
• pnpm format — clean.
• e2e for this model not run (spends real provider money); recommend /e2e after review.
