v1.7.7

cerebroAppLite 1.7.7

Multiple data sets (multi-crb)

• Dataset switcher: createShinyApp() now accepts a named vector of several
  .crb files and renders a "Select dataset:" dropdown in the sidebar, letting
  users move between data sets without restarting the app. Single-file usage is
  unchanged and shows no switcher. By default the smallest file is loaded first
  (crb_pick_smallest_file, default TRUE).
• URL selection: a data set can be opened directly via the URL, matched by
  the name given in cerebro_data or by file basename — either as a query
  string (?dataset=TCR) or as the last path segment (/TCR).
• Demo data sets: three genuinely distinct demo .crb files ship in
  inst/extdata/v1.4/ — demo_full_tcr_bcr.crb (all cells, TCR + BCR),
  demo_healthy_t.crb (T + monocytes, TCR) and demo_bcell_rich.crb (B-cell
  rich, BCR). They differ in cell composition, so the UMAP and cell-type mix
  change as you switch, and clonotypes are assigned by lineage (TCR to T cells,
  BCR to B cells) rather than at random. Group-level analyses (marker genes,
  most-expressed genes, enriched pathways) are filtered to the cell types kept
  in each subset, so the demos are internally consistent. Built from the public
  10x Genomics vdj_v1_hs_pbmc3 dataset; see data-raw/README.md for the
  reproducible build. The bundled app (shiny::runApp("inst")) now opens on
  these three data sets so the switcher is visible out of the box; pass a named
  vector to createShinyApp() for your own data (see vignette("multi_crb")).
  New vignette: Loading multiple data sets (multi-crb) with a dataset
  switcher.

Immune repertoire

• Clonal UMAP no longer renders blank when the Immune repertoire tab is
  opened after visiting another tab (e.g. Main). The plotly renderer was gated
  on server-reported plot dimensions, which are not yet available when its
  output element is created on tab switch; plotly sizes itself client-side, so
  that gate was removed.

What's Changed

• feat: multi-dataset switcher (multi-crb) + Clonal UMAP fixes by @duocang in #68
