### 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.

The Bedrock-specific tests and compile-only package check pass.
