sjfhsjfh f1dce07789 feat(spec): build out System layer and element schema model
Picture the whole framework, then pin the element-kind language layer.

System platform layer — rebuild the semantics likec4 can't draw (ADR-0001..0004):
- Prelude: opaque Identifiers carrier (ProjectId/RunId/SessionId/Principal)
- System/Run: RunState + Terminal subset (set completeness left OPEN, no invented pending)
- System/Lock: lock owner=run (typed), LockTable exclusivity, WellFormed invariant
  (a lock holder must be a non-terminal run — couples Lock and Run)
- System/Permission: read<edit<manage role lattice, capability derivation,
  can_mono monotonicity theorem; force-release sits outside the lattice (admin-only)
- System/Audit: intentionally thin (mostly plumbing, OPEN)

Courseware product layer — split the single Lesson file into focused modules and
fix doc tautology: Primitives / Element / Lesson / Render / Diagnostic, plus
QuestionBank and Course skeletons (core relations OPEN, not invented).
Diagnostic upgrades WarnsIgnored into a severity-tagged checker rule.

Element schema + rich-content model (ADR-0006, ADR-0007):
- docs/adr/0006: kind schema is declarative JSON Schema; field types are built-in
  scalars plus a `content` extension; a `content` value is typst source taken as
  module body; rich content must carry a VirtualPath (else click-to-jump and
  relative import break — verified against typst source); import boundary =
  within the engineering file + @package
- docs/adr/0007: on-disk form is a real directory tree (agent/grep friendly);
  VirtualPath = real relative path; layout conventions deferred
- spec/Courseware/RichContent: prose anchor for rich content (opaque VPath,
  RichContentRef); ElementData kept abstract — JSON/typst internals are
  implementation detail, not contract

lake build green (18 jobs), no sorry, toolchain v4.31.0.

# Lesson —— 单节课工程文件
ADR-0005:一个工程文件 = 一节课,是 element 实例的**有序序列**。课程/单元不是工程
文件,而是 lesson 的编排(见 `Spec.Courseware.Course`,OPEN)。

namespace Spec.Courseware
/--
一节课(`PINNED`, ADR-0005)。
用 `List` 而非 `Multiset`/`Finset`,因为 **element 的先后次序承载教学语义**(讲义/
PPT 式的内容流,先讲定义再举例不同于反过来)。**不建模时长**:ADR-0005 决定 lesson
是内容编排而非时间轴,故这里没有"每块多少分钟"这类字段——序是结构,时长不是。
