A new package — pure-SVG token-themed chart primitives, zero deps,
SSR-safe. Slots into the existing dataviz family next to
@bytelyst/data-viz (which owns Sparkline + KpiCard + Heatmap).

Components
──────────────────────────────────────────────────────────────────
<LineChart> Wave 9.A.1
- Multi-series with per-series colour override
- Smooth (catmull-rom) or straight polyline
- 3-tick subtle Y grid + per-tick label
- SSR-safe title id via useId()
<BarChart> Wave 9.A.2
- Negative-value support via configurable baseline
- Per-bar colour override; per-bar accessible label
- Compact-K tick labels
<AreaChart> Wave 9.A.3
- Single-series with gradient fill + line stroke
- Zero-baseline included automatically when data >= 0
<Donut> Wave 9.A.4 (a)
- Categorical share-of-total ring
- Token palette walks 6 colours; per-slice override
- Empty / all-zero data renders a muted ring (no NaN slices)
- Single near-100% slice collapses to a closed ring
- centerContent slot via <foreignObject>
<Gauge> Wave 9.A.4 (b)
- Half-circle 'fuel-tank' dial
- NaN / out-of-range clamped safely
- Caption slot below the dial

Quality gates
──────────────────────────────────────────────────────────────────
✓ pnpm -F @bytelyst/charts test → 19/19 passing
- utils: 3 cases (extent / linearScale / smoothPath edge cases)
- Line: 3 cases (series count, colour override, useId aria)
- Bar: 3 cases (count, diverging negative, colour)
- Area: 2 cases (gradient + line, single-point safety)
- Donut: 4 cases (slice count, empty ring, full-ring collapse,
centerContent slot)
- Gauge: 4 cases (in-domain, clamp >max, NaN→min, caption)
✓ pnpm -F @bytelyst/charts build → tsc clean
✓ No console.log / no Math.random for ids
✓ All primitives honour the design-system anti-patterns doc
