Add plot_lineage_tree in tracksdata.functional._plot: render lineage trees with matplotlib, supporting attribute-bound node colors and sizes, time windows, and exact timestamps. Export from tracksdata.functional and add an optional `plot` extra (matplotlib). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…lineage_tree Rename color_attr/size_attr to color/size and let color, size, marker, and text each accept either a fixed value or a callable resolving a per-node value from the node's attribute row: - color: numeric attr or callable returning numbers -> cmap + colorbar; callable returning literal colors (names/hex/RGBA) -> used verbatim. - size: attr mapped to size_range, callable returning raw sizes, or constant. - marker: single glyph, or callable returning a per-node glyph (nodes are grouped by glyph, one scatter call per group, sharing one normalization). - text: attr name or callable -> per-node annotation, styled via text_kwargs. Add `attrs` to declare the node keys callables read. If a callable is given without `attrs`, warn and load all node attributes (may pull mask blobs).

Plotting lineage trees of tracksdata in matplotlib. I believe this is of interest to a fraction of users!
