## Summary
This PR re-enables the Go test steps in CI that were previously
commented out, and fixes all compilation errors that have accumulated in
`internal/entity/models/` since the `ListModels` return type was changed
from `[]string` to `[]ListModelResponse`.
## Changes
### CI (`.github/workflows/tests.yml`)
- Re-enable **Prepare test resources** step (clones resource repo with
WordNet data)
- Re-enable **Test Go packages** step (runs `go test ./internal/...`)
- Fix resource path race condition by using
`/tmp/resource-${GITHUB_RUN_ID}` instead of `/tmp/resource`
- Exclude `/cli` package from Go tests (contains `main` redeclarations)
### Test fixes (16 model provider test files)
All errors were caused by the upstream change from `[]string` to
`[]ListModelResponse` in the `ListModels` interface:
- Add `joinModelNames` test helper to extract `.Name` from
`[]ListModelResponse` slices
- `strings.Join(models, ",")` → `joinModelNames(models, ",")` (11 files)
- `ids[i] != "..."` → `ids[i].Name != "..."` (cometapi, mistral)
- `got[i] != want[i]` → `got[i].Name != want[i]` (bedrock)
- `[]string` return types → `[]ListModelResponse` (google)
### Pre-existing bugs in model_test.go
Bugs introduced by the upstream `entity/` → `entity/models/` directory
rename:
- Add missing `pm := GetProviderManager()` calls in 3 test functions
- Fix `InitProviderManager` signature (`_, err :=` → `err :=`)
- Fix `MaxTokens` `*int` dereference (6 comparisons)
- Fix `readProviderConfig` relative path (3 levels up instead of 2)
### model.go
- Add `findRepoRoot()` to make `conf/all_models.json` resolution work
from any CWD, fixing `TestSiliconFlowProviderConfigLoadsLatestProModels`
### Test validation
```bash
go build ./internal/... # ✅
go test ./internal/entity/models/... -count=1 # ✅ all pass
```

### What problem does this PR solve?
Fixes#15542.
AWS Bedrock support for the Go model provider layer was added in #15166,
but embedding support was intentionally left out of scope and
`BedrockModel.Embed(...)` still returned the `no such method` sentinel.
This PR implements Bedrock text embeddings under the umbrella provider
tracker #14736.
### What this PR includes
- `internal/entity/models/bedrock.go`: implement
`BedrockModel.Embed(...)` through Bedrock Runtime `InvokeModel` with
existing SigV4 auth, region resolution, and runtime URL helpers.
- Titan embeddings: supports `amazon.titan-embed-text-v1` and
`amazon.titan-embed-text-v2:0`; v2 forwards `EmbeddingConfig.Dimension`
as `dimensions` when provided, while v1 keeps the payload minimal.
- Cohere embeddings: supports `cohere.embed-english-v3`,
`cohere.embed-multilingual-v3`, and `cohere.embed-v4:0`; batches input
texts and maps returned vectors to RAGFlow `EmbeddingData` in input
order.
- `conf/models/bedrock.json`: adds the `embedding` URL suffix (`invoke`)
and Bedrock embedding model entries.
- `internal/entity/models/bedrock_test.go`: adds unit tests for Titan,
Cohere, typed Cohere responses, validation, empty input, unsupported
models, and HTTP error propagation.

### Type of change
- [x] New Feature (non-breaking change which adds functionality)
### How was this tested?
- [x] `jq empty conf/models/bedrock.json`
- [x] `git diff --check`
- [x] `go test ./internal/entity/models/... -run Bedrock -count=1`
- [x] `go test ./internal/entity/models/... -run '^$' -count=1`
- [x] `go test ./internal/entity/models/... -run Bedrock -race -count=1`
Note: `go test ./internal/entity/models/... -count=1` currently fails in
unrelated existing Astraflow coverage
(`TestAstraflowEmbedReturnsNoSuchMethod` panics in
`internal/entity/models/astraflow.go`). The Bedrock-specific tests and
compile-only package check pass.
## Summary
Closes#15165.
Implements the AWS Bedrock model provider for the Go API server, tracked
under #14736. Adds Converse + Converse-Stream chat and foundation-model
listing, with SigV4 signing over a hand-rolled `net/http` path that
matches the established pattern in `internal/entity/models/` (no new
direct `go.mod` deps).
## Linked tracker
Tracked under #14736 (Implement model providers of RAGFlow API server in
Go). Closes#15165.
