/**
 * Task #242 (B1) — Capability 通用框架的核心表(只登记不调度)。
 *
 * 设计语义:
 *   - `capabilities`               一行 = 一个 capability(ligand_screening / target_discovery / ...)
 *   - `capability_lifecycle_events` 状态转换审计(B5 才真正驱动 evolution)
 *   - `capability_inner_loop_runs` 内循环执行轨迹(只记录,B5 才调度)
 *   - `capability_data_foundation` 自产数据基座(B2 已建,本任务保留)
 *   - `capability_external_knowledge_calls` 6 类适配器调用 telemetry(B2 已建)
 *   - `network_dispatch_violations` input_contract ajv 校验未通过的行(本任务漏洞 2)
 *
 * 重要:本任务 5 个抽象骨架模块(registry/lifecycle/inner-loop/data-foundation/
 * external-knowledge)只接口不实现;真实现在 B2/B5/B7。这些表在 B1 落地是
 * 为了让"接口骨架返回值"有地方写,避免后续骨架接口改动连带 schema 漂移。
