Add AWS Bedrock provider (Converse + ConverseStream)

 ## Unreleased
 
 - Use a JSON-RPC `ping` (instead of `initialize`) for the OAuth auth-discovery probe, so the probe POST is never counted as a real handshake by servers or tests that track requests by method name.
+- Add AWS Bedrock provider using the native `Converse`/`ConverseStream` APIs with bearer-token auth, supporting models not available on Bedrock's OpenAI-compatible endpoint (e.g. Claude inference profiles). #254

+=== "AWS Bedrock"
+
+    Uses the native Bedrock `Converse`/`ConverseStream` APIs, so models that are not exposed on Bedrock's OpenAI-compatible endpoint (e.g. Claude inference profiles) are reachable.
+
+    Authentication uses a bearer token (`AWS_BEARER_TOKEN_BEDROCK`); the region is part of the runtime URL. `models` are Bedrock model ids or inference-profile ids.
+
+    1. Login via the chat command `/login`.
+    2. Type 'bedrock' and send it.
+    3. Specify your API key, runtime URL and at least one model.
+    4. Done, it should be saved to your global config.
+
+    or manually via config:
+
+    ```javascript title="~/.config/eca/config.json"

+          "api": "bedrock",

 === "Mistral"
 
     The property `max_completion_token` is set to `null`, because Mistral does not support it.
