v1.0.1

Fixes

• Hover tooltip crash: hovering a shape that momentarily doesn't intersect the FIR (an empty area) no longer throws — updateTooltip now skips areas with no fillable ring.
• Empty intersection: clip() treats a valid-but-empty JSTS result as a genuine no-overlap (instead of passing an empty geometry downstream).
• Latitude band: a reversed-but-legal encoding (N OF N54 AND S OF N50) is now sorted so south ≤ north instead of building a degenerate rectangle. Longitude bands are left untouched (a west > east band legitimately crosses the antimeridian).
• Antimeridian detection is now structural — the FIR touches both ±180 edges (split form) or has an edge jump > 180° (jump form) — instead of a bbox-width heuristic that could misfire on a very wide non-crossing FIR.
• MapLibre: a drag released outside the map canvas no longer leaves panning disabled (a window-level mouseup finishes the drag, mirroring the OpenLayers adapter).

Internal

• OpenLayers hit-testing forwards the full feature property bag (parity with MapLibre).
• Removed the unused setCursor from the public MapAdapter interface (kept private in each adapter).
• Documented the tropical-cyclone placeholder centre (toArea) and the process-global toolbar <style> injection.
• Added prepublishOnly (build + test) and engines.node >= 18.
• Tests: +17 (tooltip style merge, latBand sorting, toolbar 12-position layout, SigmetToolbar controller); added jsdom for the DOM-level toolbar tests.
