### What problem does this PR solve? The VolcEngine Go driver in `internal/entity/models/volcengine.go` shipped with a `ListModels` stub that returned `volcengine, no such method`. `conf/models/volcengine.json` also did not declare a `models` URL suffix, so the model picker had nothing to call even if the method body were filled in. A tenant who configured Volcengine (Doubao / Ark) as a provider could not see the list of available endpoints from the RAGFlow UI. Several other Go drivers already implement `ListModels` against the OpenAI-compatible `/models` endpoint (deepseek, gitee, nvidia, openai, siliconflow), so the interface and pattern are well-established. This PR fills the gap. ### What this PR includes * `conf/models/volcengine.json`: declare the `models` URL suffix alongside the existing `chat`, `files`, and `embedding` entries. The Ark v3 API exposes `https://ark.cn-beijing.volces.com/api/v3/models`, so the suffix is just `models`. * `internal/entity/models/volcengine.go`: replace the `ListModels` stub with a real implementation. Reuses the package-level `DSModelList` / `DSModel` types that DeepSeek, Gitee, and SiliconFlow already use to parse the OpenAI-compatible models response shape. No factory change. No interface change. ### How the driver works * Resolves the region with a default fallback, the same way the other VolcEngine methods in this driver already do. * Builds the URL from `BaseURL[region] + URLSuffix.Models`, with `strings.TrimSuffix` on the base to keep the join robust. * Issues a `GET` with optional `Authorization: Bearer <api_key>` (the header is omitted when no key is configured, mirroring the existing NVIDIA `ListModels`). * Reads the response body once, surfaces a non-200 with the upstream status line plus body, and parses the JSON via the shared `DSModelList` type. * Returns the model id list in input order. When the response includes an `owned_by` field, the entry is rendered as `id@owned_by`, matching the convention used by the other Go drivers. ### Type of change - [x] New Feature (non-breaking change which adds functionality) ### How was this tested? * `go build ./internal/entity/models/...` returns exit 0. * `go vet ./internal/entity/models/...` is clean. * `gofmt -l internal/entity/models/volcengine.go` is clean. * The full method set on `VolcEngine` still matches the `ModelDriver` interface. * Endpoint reachability check: `GET https://ark.cn-beijing.volces.com/api/v3/models` returns `401 Unauthorized` without an API key, confirming the path exists and accepts Bearer authentication. * Pattern parity with DeepSeek, Gitee, NVIDIA, and SiliconFlow `ListModels`.
