feat: OpenCode执行层试点 — 补测试5个 + list_objectives隔离修复

- OpenCode执行模式: 补 test_maps.py 5个测试(create_objective/snapshot隔离/entity注入/跨企业)
- OpenCode诚实标注: list_objectives 后端漏entity过滤 → 修复(跨企业返回空)
- 记忆层闭环: Hermes验证(pytest 536 passed) + 技能已更新(opencode-independent-review 双角色)
- 执行层试点验证: OpenCode能写代码+发现后端缺口, 最小闭环跑通
