Discharge the layout question ADR-0007 deferred. Fix the engineering-file
on-disk arrangement so the checker recovers lesson order/membership without
evaluating typst:
- manifest.toml at root: [project] + [info] + ordered [[parts]] (kind+path) +
[targets.*]. Array order IS lesson order (ADR-0005). Subsumes the samples'
project.toml/info.toml and replaces main.typ's `#let parts`.
- element.toml per element folder: explicit kind + scalar fields (self-describing,
parent-dir grouping not load-bearing).
- content fields are convention-named <field>.typ siblings; the kind's JSON Schema
(ADR-0006) is the source of truth for which .typ files must exist. Drops the
samples' per-element main.typ wiring (now generated, not hand-authored).
Surfaced gaps (deferred): per-file render override (ADR-0005 says the matrix is
overridable in-file; MVP keeps rules in the render layer, no override), 题库
on-disk layout, manifest richness (per-part metadata, sectioning).
