test(contract): 第2刀c Go 契约快照(/v1/me·usage·UsageEntry)+ Go CI job
支柱 2(契约单源)后端守门 + 两端对账:
- httpapi/contract_test.go：冻结 /v1/me 字段面(12 key,与 Dart _frozenMeKeys 对账,
注明后端多发 uuid/dp_uuid + expire_at 别名)
- usage/contract_test.go：冻结 /v1/usage(UsagePoint)、/v1/usage/devices
(DeviceUsagePoint + envelope)字段面
- pb/agentv1/contract_test.go：冻结 agent↔控制面 UsageEntry 字段面
- ci.yml：新增 go-server job(golang:1.25 build+test)——此前 server 测试未进 CI
- 本地:5 契约用例 + 全量 go test ./...(25 包)绿
