Adds ChainAgent.test.ts (12 tests) covering constructor validation, the chaining pipeline, passthrough of additionalParams, streaming on the last agent, error propagation, and defaultOutput fallback. Adds BedrockFlowsAgent.test.ts (8 tests) covering constructor options, processRequest happy path, custom encoder/decoder, missing response stream, and client error wrapping. Closes 2FastLabs#539

Adds unit test coverage for two previously untested TypeScript agents:
ChainAgent.test.ts(12 tests)processRequest: single-agent pass-through, multi-agent pipeline (output of agent N becomes input to agent N+1),additionalParamsforwarded to every agent, default response on empty content, last-agent streaming allowed, intermediate streaming returns default response, agent error propagatesBedrockFlowsAgent.test.ts(8 tests)enableTracedefault/setprocessRequest: happy-path flow invocation + decode, missing response stream error, customflowInputEncoder, customflowOutputDecoder, client-level error wrappingBoth files follow the same mock/describe/it structure as the existing
LambdaAgent.test.ts.User experience
Before:
npx jestproduced no output forChainAgentorBedrockFlowsAgent.After: 20 new assertions covering the core behaviour and error paths of both agents.
