v1.11.0

Large-AnnData usability, a Debian package, and build/CI maintenance.

Added

• --tab <name> — view a named component tab (AnnData obs / var / X,
  a workbook sheet, …) straight from the CLI, e.g.
  vv cells.h5ad --tab obs -n 20. Case-insensitive; an unknown name lists the
  available tabs. The data components were previously only reachable in the
  interactive TUI.
• Debian package — packaging/debian/build-deb.sh wraps the static
  AlmaLinux 8 binary into a self-contained .deb (Depends: libc6 only), and
  the release workflow now publishes a vv_<version>_<arch>.deb for x86_64 and
  aarch64 alongside the tarballs.

Fixed

• Large AnnData components no longer stall. Opening a multi-GB .h5ad
  (e.g. a 100M-cell atlas plate with a 4.7M-row obs) used to hang for minutes:
  the TUI eagerly materialised every component and read obs/var in full.
  Now each component tab is built lazily (only when viewed), and obs/var/X
  are read as a bounded first-rows preview (footer notes the true size). A
  high-cardinality categorical (e.g. a per-cell barcode with millions of
  categories) is shown as integer codes instead of reading its whole dictionary.
• Arrow deprecation warnings in the Parquet read paths silenced by moving to
  the arrow::Result overloads of ReadRowGroups / GetRecordBatchReader
  (version-guarded so the Arrow 23.0.1 static build still compiles).

Build / CI

• ncurses is fetched from the GNU mirror (ftp.gnu.org) instead of
  invisible-mirror.net, which intermittently WAF-blocked CI runners and broke
  a release.
• GitHub Actions bumped to their Node 24 runtimes ahead of the forced migration.
