actop 1.4.11

Changed

• TUI: the P-CPU and E-CPU clusters now render as two separate titled boxes
  (previously two halves of a single "CPU" box), so each cluster's chart stands
  out as a sibling alongside GPU. The grid preset lays them out as the top row,
  with GPU·ANE / Memory on the next row and Power spanning the full width beneath.
• TUI: per-core panels are now hidden by default. With cores off, the
  P-CPU / E-CPU / GPU charts read as the prominent sibling boxes. --show_cores
  still opts into showing them at startup; the new c key toggles them live.

Added

• TUI c key: toggle the per-core panels on/off at runtime (independent of the
  --show_cores startup default). Painted immediately on show, no sample wait.

Docs

• docs/DESIGN-system.md §5: sync the layout prose to the five-box grid
  (P-CPU / E-CPU / GPU·ANE / Memory / Power), the per-core toggle, and the
  same-row boundary alignment; CLAUDE.md architecture table updated to match.
• docs/TODO-architecture-roadmap.md: add a "Nice-to-Have — Distribution & UX"
  item for an update-available notice (startup banner + title/status token,
  PyPI-version check, off-render-path and fail-silent, opt-out + cached).
