New "Grafiek" slide type rendering bar, line and pie charts.
Storage fits Marp: a ```chart fenced block holds the spec as JSON. Small
charts keep their data inline (the .md stays self-contained); data-driven
charts link an external CSV via "source": "data/<name>.csv" kept in a
separate data/ directory and packaged into .ocideck like images. On save
the inline data is stripped for linked charts (the CSV is the source of
truth); on open it is re-hydrated from the CSV.
- lib/models/chart.dart: ChartSpec/ChartSeries JSON parse/serialize,
inline-vs-source handling, and a CSV parser.
- In-app rendering (preview/presenter/PDF/PPTX) via fl_chart.
- HTML export renders charts as self-contained inline SVG generated in
Dart (no JS chart library); export inlines linked data so the page is
standalone.
- Editor: type picker, title, a CSV-style data field, and CSV import that
can inline the data or link it as data/<name>.csv (with unlink).
- Markdown round-trip + .ocideck packaging of linked CSVs; translations
for all supported languages.
flutter analyze is clean, all tests pass (new chart/CSV/round-trip tests),
and the macOS debug build compiles.

Draw on slides while presenting, kept as a layer fully separate from the
Marp content so the deck stays pure, portable Marp.
Presenter tools (D pen, T highlighter, E eraser, X laser, C clear, Esc
puts the tool away) with a small floating colour/tool bar shown only when
a tool is active. Strokes use coordinates normalized to the 16:9 slide so
they render identically on the laptop and the beamer; in dual-screen mode
the ink and the laser are mirrored live to the audience window.
Persistence (decoupled from the .md):
- In memory the layer is keyed by Slide.id (stable within a session).
- On disk it lives in a sidecar <name>.ink.json next to the deck and as a
separate entry inside the .ocideck package; the markdown is untouched.
- Because slide ids are regenerated on load, the sidecar anchors strokes
by order + a content fingerprint, re-attaching them after reordering and
dropping them when a slide's content changed.
- Deck.annotations carries the layer in memory but is never serialized to
markdown; deckProvider.setAnnotations keeps it out of undo/redo.
flutter analyze is clean, all tests pass (incl. new stroke/codec tests),
and the macOS debug build compiles. Drawing and live beamer sync still
need verification on real hardware.
