## Summary
- Verify and populate `content_length` (context window) and `max_output`
(max generation tokens) for all **478 chat/vision models** across **47
provider configs**
- Data sourced from **official API documentation** via 12 parallel
agents + targeted web verification
- Update Go test assertions to match verified values

### What problem does this PR solve?
Adds the missing Anthropic provider implementation for the Go model
provider layer.
Closes#14939
### What changed
- Add `conf/models/anthropic.json` with Anthropic Claude chat/vision
models and API endpoints.
- Add `internal/entity/models/anthropic.go` implementing non-streaming
Messages API chat, model listing, and connection checking.
- Register `anthropic` in the Go model factory.
- Add httptest coverage for headers, payload mapping, response parsing,
validation errors, provider errors, model listing, connection checking,
factory registration, and unsupported methods.
### Notes
Streaming chat is left as an explicit `no such method` follow-up because
this initial provider focuses on non-streaming chat and connection
checking.
### Tests
- `docker run --rm -v
/home/ubuntu/Documents/gitTensor_repos/carlos/ragflow:/work -v
/tmp/ragflow-go-cache:/go/pkg/mod -v
/tmp/ragflow-go-build:/root/.cache/go-build -w /work golang:1.25 go test
-vet=off ./internal/entity/models -run Anthropic -count=1 -v`
- `docker run --rm -v
/home/ubuntu/Documents/gitTensor_repos/carlos/ragflow:/work -v
/tmp/ragflow-go-cache:/go/pkg/mod -v
/tmp/ragflow-go-build:/root/.cache/go-build -w /work golang:1.25 go test
-vet=off ./internal/entity -count=1`
- `git diff --check`
- `jq . conf/models/anthropic.json >/dev/null`
Plain `go test ./internal/entity/models` currently hits pre-existing
unrelated vet findings in other provider files (`baidu.go`, `cohere.go`,
`fishaudio.go`, `openrouter.go`).
