* feat(data): add ICESat-2 and GEDI spaceborne LiDAR footprints Add Data -> ICESat-2 / GEDI reads a local HDF5 granule of ICESat-2 ATL06/ATL08 or GEDI L2A/L2B/L4A in the browser (h5wasm) and adds its footprints as a GeoJSON point layer. The NetCDF reader skipped these products because their per-footprint arrays are 1-D. The reader picks a product description from the root short_name (or the DAAC file name), lists beams and every 1-D field aligned with the footprints, applies the product's quality flag and fill values, and adds beam, beam type, UTC time and along-track distance to each feature. It can limit the read to the current view and thins every beam evenly to a point cap. The new layer is colored by the product's main field, so the attribute table charts give an along-track profile. Refs #3078 * Address review feedback - Thin footprints with one stride over all beams' matches, so maxPoints caps the total; restarting the index per beam kept the first match of every beam and could exceed the cap (CodeRabbit). - Null 64-bit integer fields that equal their _FillValue, compared as BigInt so the fill is not lost to float64 rounding (Claude). - Fit a track that crosses the antimeridian with unwrapped bounds instead of zooming out to the whole world; pointBounds moves to lib/ so it can be unit-tested (Claude). * Address review feedback - Fall back to the default point cap when the Maximum footprints box is empty or invalid, instead of lifting the cap and building a million-feature layer from a full GEDI orbit (Claude). - Compare a numeric 64-bit _FillValue only when it is a safe integer, as a BigInt, so a rounded fill cannot null a neighboring shot number; test added (CodeRabbit). * Address Claude review feedback - Drop an Add whose granule was closed during the pre-read yield (dialog closed or another file picked), instead of reading the closed file and reporting "No footprints matched" for the wrong granule. * Address Claude review feedback - Say what the quality filter does for each product under the checkbox, and relabel it "Apply the product's quality filter": ATL08 has no quality flag and only drops segments without a terrain height, so "pass the product's quality flag" overstated it. - Drop the unreachable shift in pointBounds: the shifted range is only narrower when points straddle 180°, which keeps west360 in [0, 180]. * Address CodeRabbit review feedback - Clear the busy state when another file is picked: a submit superseded during its pre-read yield returns early without clearing it, which left the Add button disabled for the newly opened granule. * Address Claude review feedback - Clamp a fractional maxPoints to at least 1, so 0.5 no longer floors to 0 and yields an infinite stride. - Keep the first field with a name and rename only later duplicates to their path, so a product's default names (and the color-by primary field) stay stable when another dataset shares a name. * feat(data): ICESat-2/GEDI sample granules, resizable dialog, Files section - Add a Sample data dropdown with one granule per product (ATL06, ATL08, GEDI L2A/L2B/L4A) hosted on Source Cooperative, downloaded with a progress readout into a preallocated buffer and cancelled when the dialog closes or another file is picked. - Stop the horizontal scrollbar: the dialog body is a grid whose column grew to the longest unbreakable HDF5 path (ATL06), so the form gets min-w-0 and field paths truncate. - Widen the default dialog and add a corner resize grip, through a useDialogResize hook that follows the layer metadata dialog's grip. - Move the menu entry from 3D layers to Files: the footprints render as flat points read from a granule file. * Split the ICESat-2/GEDI dialog and handle encoded sample downloads - check:untested-modules failed: the dialog reached 615 lines with no test loading it. Move the sample list, downloadWithProgress, fieldKey and baseName into lib/spaceborne-lidar-samples.ts (with tests), and the beam/field/filter controls into SpaceborneLidarOptions.tsx; the dialog is now 435 lines. - Read a content-encoded response whole instead of preallocating from Content-Length, which is the compressed size there and would overflow the buffer (Claude review).
