Add sequential coverage for signature reset.
MiniMaxHandler stores the signature on the handler instance, and prepareApiConversationMessage reads it for later history. The current test uses one stream, while each test creates a fresh handler. Add a test that completes a signed request, completes a second request without a signature_delta, and asserts handler.getThoughtSignature() is undefined. Without this coverage, removing the reset can leave the previous signature available for the next request.

Add strict coverage for unsigned thinking blocks.
convertToBedrockConverseMessages accepts a thinking block without signature and omits that property from reasoningText. The current test covers only the signed path. Add an unsigned fixture and use toStrictEqual or not.toHaveProperty("signature") so the test detects an unconditional signature: undefined. The signed test only detects removal of a provided signature.

Closes: #1665
Description
reasoningand signedthinkingblocks into Bedrock ConversereasoningContentinstead of the literal[Unknown Block Type]placeholder.signature_deltaevents so the task history can store valid signedthinkingblocks for the next tool-loop request.reasoningblocks are removed.MiniMax's Anthropic-compatible API requires replaying the complete signed thinking block unchanged. Capturing its streamed signature preserves continuity without sending an unsupported internal block shape.
Test Procedure
Using the repository-required Node.js 22.23.1:
Results: 4 test files / 69 tests passed; type checking and ESLint passed. Suppression counts did not increase.
Pre-Submission Checklist
Visual Snapshots
Not applicable; no UI changes.
Videos (interaction / animation only)
Not applicable; no UI changes.
Documentation Updates
Additional Notes
The MiniMax behavior follows its official Anthropic-compatible API requirement to retain both thinking text and signature during tool-use conversations.
