Release 4.4.5

Changes from 4.4.3 to 4.4.5

Note: 4.4.4 was skipped due to a failure during the release process.

This release promotes the b2view terminal viewer to a core feature —
installed by default, with new interactive row and column filtering — and
makes BatchArray block layouts (and hence compression ratios) reproducible
across CPUs.

b2view, the terminal data viewer

• Installed by default: textual and rich are now regular
  dependencies, so the b2view CLI works out of the box (the [tui] extra
  is gone). A getting-started walkthrough was added to the docs, and the
  README now lists the CLI tools.
• Row filtering: pressing f on a CTable node opens a modal that takes
  the same string expressions as CTable.where() (dotted nested names,
  and/or) and pages through the matching view. Filters are remembered
  per node for the session, the data header shows the active filter plus
  the unfiltered total, and escape (or an empty expression) clears it.
• Column filtering: / narrows the visible columns by case-insensitive
  substring; column paging and the c goto-column modal then operate on
  that subset. Combines freely with the row filter; escape clears one
  layer per press (rows first, then columns).
• Mouse handling: the terminal owns the mouse by default, so native
  text selection/copy works like in any CLI program; --mouse lets b2view
  capture it instead (click-to-focus, wheel scrolling by half a page,
  paging at the edges).
• Navigation: ? opens a help screen listing all keys; c jumps to a
  column by index, exact name or unique name prefix; s/e jump to the
  first/last column window; row paging and jumps keep the cursor on its
  column; dim-mode index/viewport movements clamp at the boundaries instead
  of wrapping around.
• Rendering: column windows are fitted from measured rendered widths
  (and re-fitted on terminal resize and panel maximize/restore), and float
  columns use a uniform number of decimals so decimal points align down
  the column.
• Test suite: first automated tests for the TUI — Pilot-driven keyboard
  journeys against a deterministic generated store (marker tui), plus
  render unit tests. Skipped on wasm, where Textual apps cannot start
  (no termios).

BatchArray

• Reproducible block layouts: automatic variable-length block sizing
  now uses fixed byte budgets (1 MiB for clevel 1-3, 8 MiB for 4-6, 16 MiB
  for 7-8) instead of the CPU cache sizes, so the layout — and hence the
  compression ratio — no longer depends on the machine that created the
  array.

Build and docs

• Installing test dependencies: the docs now use
  pip install . --group test (a PEP 735 dependency group); the stale
  [test] extra syntax was removed.
• cibuildwheel updated to 4.0.
