### What problem does this PR solve?
The Gitee AI Go driver in `internal/entity/models/gitee.go` shipped with
a stub `Encode` method that returned `gitee, no such method`, even
though `conf/models/gitee.json` already wires the `embedding` URL
suffix. The conf also listed no embedding models, so the picker had
nothing to select.
This blocked any tenant who wanted to use Gitee AI for chat, rerank
(already working, see #14656), and embeddings from a single provider.
This PR fills the gap, mirroring the just-merged Aliyun `Encode`
(#14647):
- `internal/entity/models/gitee.go`: replace the `Encode` stub with a
real implementation.
Validates inputs, resolves the region with a default fallback, POSTs the
standard OpenAI-compatible `{"model", "input": [...]}` body to
`BaseURL[region] + URLSuffix.Embedding`, parses `data[*].embedding`
indexed by `data[*].index` so output order matches input order, handles
both `float64` and `float32` element types, and uses a 30s per-call
context deadline matching the merged `Rerank`.
- `conf/models/gitee.json`: add `BAAI/bge-m3` so the embedding picker
has something to select.
No factory change. No interface change. No URL suffix change.
Verified with `go build`, `go vet`, and `gofmt -l` : all clean.
Closes#14697

### What problem does this PR solve?
The Gitee AI Go driver shipped with a stub \`Rerank\` method that
returned \`Rerank not implemented\`, even though
\`conf/models/gitee.json\` already wires the rerank URL suffix at
\`\"rerank\": \"rerank\"\`. The same config did not list any
rerank model, so the picker had nothing to select.
So a Gitee tenant could not use BAAI/bge-reranker-v2-m3 as a reranker
through the Go layer today, even though the
infrastructure was one config entry and one method body away.
### What this PR includes
- \`conf/models/gitee.json\`: add \`BAAI/bge-reranker-v2-m3\` to the
\`models\` array.
- \`internal/entity/models/gitee.go\`: replace the \`Rerank\` stub with
a real implementation. Adds two small local types
that match the OpenAI-compatible \`/rerank\` shape already used by the
SiliconFlow and ZhipuAI drivers.
No factory change. No interface change.
### How the driver works
- Validate \`apiConfig\` and the API key, validate the model name,
resolve the region with a default fallback, build the
URL from \`BaseURL[region] + URLSuffix.Rerank\`.
- Use a per-call \`context.WithTimeout(30s)\` and
\`http.NewRequestWithContext\`, matching the pattern the
recently merged Aliyun Encode and the OpenAI driver already use.
- Send \`{model, query, documents, top_n, return_documents:false}\` in
the body.
- Parse \`results[*].relevance_score\` and copy each score into the
output slice indexed by \`results[*].index\`, so the
output order matches the input order even if the API returns items in a
different order.
- Empty input returns \`[]float64{}\` with no HTTP call.
- An out-of-range result index returns a clear error rather than
silently skipping the entry.
- Non-200 responses propagate the upstream status line and body.

### How was this tested?
- \`go build ./internal/entity/models/...\` in a clean go 1.25 image
returns exit 0.
- The full method set on \`GiteeModel\` still matches the
\`ModelDriver\` interface.
- Pattern parity with the existing SiliconFlow Rerank and the recently
merged ZhipuAI Rerank (#14608).
Closes#14655
### What problem does this PR solve?
1. **Implement `OpenRouter` Provider:** Fully support OpenRouter AI
models (e.g., `gemma`, `minimax`). Includes robust handling of
Server-Sent Events (SSE) streams, error event interception, and proper
parsing of both `reasoning_content` and standard `content`.
2. **Fix BaseURL Resolution Bug:** Fixed a critical edge case in region
configuration parsing. Added a strict empty string check
(`*apiConfig.Region != ""`) alongside the `nil` check. This ensures that
if the UI passes an empty string, the system correctly falls back to the
`"default"` region, preventing `unsupported protocol scheme ""` errors
during HTTP requests.
