actop 1.4.0

Added

• TUI layout PR2 (layout presets) — the dashboard now ships two arrangements of
  the same four sections, switchable live:
  • grid (new default): two columns — the CPU section spans the full left
    column, GPU·ANE / Memory / Power stack in the right column. Fits short
    terminals without scrolling (~28 rows incl. chrome).
  • stack: the previous single full-width scrolling column — longest chart
    history span.
• --layout {grid,stack} CLI flag (default grid) and a matching
  DashboardConfig.layout field.
• l key cycles the layout preset (grid ⇄ stack) live, with zero data loss
  (history deques are untouched by a switch); documented in the help overlay
  and footer.
• Auto-degrade: a requested grid narrower than ~96 columns renders as stack
  automatically and recovers when the terminal widens, so the two columns never
  squeeze below readability. HardwareDashboard.effective_layout_preset exposes
  the applied preset vs. the requested layout_preset.

Changed

• The process table is now a fixed 74-column panel (was 1fr); the dashboard
  absorbs the remaining width. Dashboard/section CSS moved into
  HardwareDashboard.DEFAULT_CSS (scoped to the widget) — the presets are a CSS
  class swap there, not app-level layout.
• Width-adaptive rows (inline power sparks, core grids) now re-render on a
  terminal resize or preset swap instead of waiting for the next sample.
