Replace generated-driver compilation with the template model.
cph-typst:
- driver.rs DELETED (generate_driver, static-include driver, numbering-threading).
- New manifest.rs: build_augmented_manifest(&Lesson) emits a TOML doc with [info]
+ ordered [[parts]] each carrying a `fields` array = the kind's content fields
whose <root>/<path>/<field>.typ exists on disk. Reuses cph-schema's
content_field_names (new dep; no cycle). This closes the OPEN point WU-C'
surfaced: typst has no file-exists primitive, so the engine (which has disk
access) tells the template which optional content (lemma proof) is present.
- World main = the real engineering-file template (<root>/<template>); the
augmented manifest is served as an in-memory virtual file at /.cph/manifest.toml
(never written to the tree), injected via sys.inputs.manifest. render_dir kept
only for @local/cph-render + vendored @preview/numbly resolution.
- Artifact handling: SingleFile+TypstCompile compiles; FileTree, shell-only, and
undeclared-target are blocking "deferred/not-declared" diagnostics (ADR-0011).
- Engine public signatures unchanged; LessonWorld::new takes template+manifest_src.
cph-check: no source change needed (only uses lesson.targets/target.name +
unchanged Engine methods); pipeline + Legal alignment intact.
Fixtures: mini gets exports/{student,teacher}.typ (from render/templates/) + v2
manifest + a second proof-less lemma to exercise optional content. render-stub
retired (tests use the real render/). Through-template PDFs offline: student 44KB,
teacher 56KB; proof-less lemma compiles clean (optional-content confirmed).
Workspace: fmt + clippy -D warnings + all tests green.

The heart of the pipeline. Embeds the typst 0.15 compiler as a library to
compile-check a lesson and export a PDF, with diagnostics mapped back to source
spans (the product's value).
- LessonWorld: a typst World over the engineering-file directory tree. vpath =
real relative path (ADR-0007); the per-target driver is mounted in-memory as
`main` (.cph/driver-<target>.typ, never written to disk); @local/cph-render is
resolved from render_dir (CPH_RENDER_DIR / with_render_dir), no package install
or network. Fonts via typst-kit FontStore (system CJK).
- Driver generation: from the manifest, per target — static root-relative
`include` of each content file (⇒ module body content, ADR-0006), assembled
into the frozen `display(info, target, parts)` call; optional lemma proof
emitted only if proof.typ exists; example `source` scalar threaded through.
- Diagnostics: typst SourceDiagnostic (errors + warnings) → cph_diag::Diagnostic.
0.15 DiagSpan handled via span.id() + WorldExt::range → file-relative
SourceSpan with 1-based line/col; driver-internal spans re-pointed with a
"generated driver" hint, never dropped. typst hints/trace carried through.
- Engine API: new / with_render_dir / compile_check / build_pdf.
- 6 tests incl. build_pdf_with_real_render — full World→driver→cph-render→PDF
producing real PDF-1.7 output (student 42KB / teacher 54KB). clippy/fmt clean.
Also fixes render/typst.toml `compiler = ">=0.15.0"` → `"0.15.0"`: typst 0.15's
manifest parser rejects a `>=` comparator on the compiler field (the 0.14 CLU
WU-2 tested against was lenient). This unblocks loading the real render package.
Pinned: typst/typst-pdf/typst-syntax/typst-library/typst-layout/typst-kit =0.15.0.

Stand up the Rust implementation of the rule-based checker (the thing that
"stands in Lean's position" at product runtime). Single repo-wide cargo
workspace at the repo root so future components (e.g. an exporter) can reuse
shared crates.
- workspace: 6 member crates under crates/; cph-schema/cph-typst/cph-check/
cph-cli are stubs for later WUs that compile clean today.
- cph-diag: shared diagnostic vocabulary. Severity { Warning, Error } mirrors
Spec.Courseware.Diagnostic.Severity exactly (two-valued, no info/note — a
contract decision documented in-code since there's no CI gate for alignment).
Closed DiagCode set with stable string forms; Diagnostic with optional span +
fix hint; Display renders `error[CODE]: msg / --> file:line:col / hint: …`.
- cph-model: the ADR-0008 loader. Reads manifest.toml ([project]/[info]/ordered
[[parts]]/[targets.*]) + each part's element.toml into an ordered Lesson
(mirrors Lean `Lesson = List (Element P)`). Structure-only: cross-checks
part.kind == element.toml kind, rejects `..` traversal; does NOT do schema
validation (WU-3), content-file existence (WU-3), or typst (WU-4).
`load(root) -> (Option<Lesson>, Vec<Diagnostic>)`: Some even on collectible
part errors, None only on hard manifest failure.
- 13 tests (7 cph-diag, 6 cph-model incl. static fixtures doubling as format
docs). build + test + clippy -D warnings + fmt --check all green.
Judgment call flagged for review: cph-diag has no ManifestMalformed code, so
manifest-structure errors map to SchemaViolation (TODO noted in-code).
