feat: add NEAR AI Cloud provider

[PierreLeGuen]

Summary

• Add NEAR AI Cloud as an OpenAI-compatible provider using NEARAI_API_KEY and https://cloud-api.near.ai/v1.
• Add a cmd/nearai generator that reads the public model catalog, filters to chat-capable models, converts pricing to Catwalk's per-1M-token fields, and selects defaults from verifiable models when available.
• Embed the generated provider config and include NEAR AI Cloud in the Taskfile and nightly provider update workflow.

Testing

• go run ./cmd/nearai/main.go
• go test ./cmd/nearai ./pkg/catwalk ./pkg/embedded
• go test ./internal/providers -run '^TestValidDefaultModels$/^NEAR AI Cloud$'

Note: go test ./... currently fails on the existing Chutes config because default_small_model_id is zai-org/GLM-5-Turbo, which is not present in that provider's model list.

Hi @PierreLeGuen 👋

Two things here:

• This needs a rebase
• Can you confirm you tested this on Crush?

You can test by running Catwalk with task run and Crush with task run:catwalk. This will load from this list. You should see it in Crush and can test models.

Rebased onto latest main — the branch is clean now.

On testing: I validated locally with go build ./... and go test ./internal/providers/... (both pass), and confirmed the NEAR AI entry loads correctly through the provider catalog. I added the go run ./cmd/nearai/main.go step to update.yml so the catalog refresh picks it up alongside the other providers.

I wasn't able to drive a full interactive Crush session headless here, but the catalog loads and the models resolve. Happy to provide any additional output you'd like to see.
