- New `GalaxyView` renders glowing stars per archetype (pulsing heartbeat),
the jump-lane web (traveled/frontier/unexplored), the charted region's
convex hull, HOME/SHIP markers, hover readouts, and CONFIRM JUMP on a
live lane (reuses the existing gate transport).
- `GalaxyChart.js` provides the pure model + geometry: edgeKey, snapshot
builder, convex hull / padded polygon, star pulse/color, and plate
clipping (Liang-Barsky + Sutherland-Hodgman) — all Node-testable.
- Run's footprint (`visitedSystems`, `usedGates`) is captured/restored/
reset in SaveData; legacy saves default to "current system charted,
nothing traveled".
- MapWindow gains tab switching between the system chart and the galaxy
view, with shared stats/legend/status chrome per mode.
- Two dev tests cover the galaxy model, save round-trip, hull geometry,
plate clipping, and a regression for the star-label blink bug.
