fix(claude): preserve per-message output_config in Claude messages - #7561
Conversation
ClaudeMessage only kept role and content, so re-marshaling a /v1/messages
request dropped the output_config of effort-only system messages
(per-message effort beta). The upstream then received
{"role":"system","content":[]} and rejected it with
"system content must contain at least one block".

- Line 140: Use OutputConfig to detect message-level output configuration and
share that detection across the primary Claude, Vertex, and AWS routes. Before
forwarding, ensure supported models receive the required capability or reject
the request; emit it via the HTTP header for Claude and Vertex, and via
AnthropicBeta for AWS.

dto.ClaudeMessage只有role、content两个字段。非透传时，relay/claude_handler.go会重新序列化请求，导致 message 上的output_config被丢弃。受影响的是官方 per-message effort (beta) 的 effort 切换消息{"role":"system","content":[],"output_config":{...}}：字段被丢掉后，上游收到空 system 消息，返回400 messages.1: system content must contain at least one block。修复方式：
ClaudeMessage新增OutputConfig json.RawMessage（json:"output_config,omitempty"）。没有该字段的 message 序列化结果不变。AWS / Vertex 渠道直接复用request.Messages，也会带上这个字段。📸 运行证明 / Proof of Work
d04c118，SQLite，Anthropic 渠道指向一个记录请求体的 mock 上游，未开透传。向/v1/messages发送含{"role":"system","content":[],"output_config":{"effort":"high"}}的请求（完整请求见 Claude Messages：message 级 output_config（per-message effort）转发时被丢弃，上游返回 400 #7563）：{"role":"system","content":[]}；{"role":"system","content":[],"output_config":{"effort":"high"}}，其余字段与请求一致。relay/channel/claude/adaptor_test.go中的TestConvertClaudeRequestPreservesMessageOutputConfig：未修复时 FAIL（actual: <nil>），修复后 PASS。cd relaykit && GOWORK=off go build ./... && GOWORK=off go test ./...：通过。go test ./relay/... ./controller/... ./service/...：只有service包中TestObserveChannelAffinityUsageCacheByRelayFormat_MixedMode、_UnsupportedModeKeepsEmpty两个用例失败，它们在未修改的d04c118上同样失败。✅ 提交前检查项 / Checklist
