chore(spec+checker): cleanup pass — trim docs, reorg Courseware, covers-as-data, fold DanglingReference (ADR-0012)

Spec母本噪音清理 + 一处 spec↔impl 对齐 + 一处契约自洽修正。

Part A — spec doc 瘦身:每条 doc 收到"语义点 + 标签 + ADR ref + 承载性 why",
把跨文件复读的方法论(element-kind 开放性对比、likec4 画不出、分歧点测试)上移到
module header。OPEN 框架保持清晰(RunState/Capability 完整性仍明示须 surface)。

Part B — Courseware/ 由 10 文件平铺重组为 Model/ Export/ Check/ Open/ 四子命名空间
(namespace Spec.Courseware 不变,零引用改动)+ 四个子 aggregator。lake build 绿(24 jobs)。

Part C — 渲染覆盖落为数据(ADR-0011 对齐):去掉 cph-check 里硬编码的
COVERED_TARGETS,改读 TargetConfig.covers。cph-model 新增 covers: Option<Vec<String>>
(None=未声明,由 cph-check 默认为全部 known kinds;显式 [] 表示不覆盖任何 kind)。
新增 3 个覆盖行为测试。

ADR-0012 — DanglingReference 退役(诊断 7→6 类):其两种情形(未解析 @ref、越界/缺失
相对 import)都是 typst 编译期失败,归 typstCompile。同步移除 Oracle.refsResolve
(被 compiles 蕴含),Legal 少一个合取项。impl 删去从未被发射的 DiagCode::DanglingReference,
闭合 named-but-unemitted 的 spec↔impl 缝。ADR-0010 加修订指针。

OPEN 点(RunState/Capability 完整性、QuestionBank、Course)按既定纪律保持 OPEN,本次
只改善其框架措辞,不决策。

验证:spec lake build 绿;cargo test 全绿(含新增覆盖测试);clippy 静默;
TH-141 check 0 errors/0 warnings 无回归。
