actop 1.4.10

Changed

• TUI charts in dots glyph mode (the default) now pack 2 time samples per
  character by using both braille dot columns (left = earlier sample, right =
  later), doubling horizontal density to a continuous btop-style line instead of
  the previous sparse single-column poles. Applies to both the section charts
  (BrailleChart._render_dots) and the inline per-core / power sparklines
  (_inline_spark), which now share one _braille_cell_bits primitive. block
  glyph mode is unchanged (1 sample/character). The chart time-span label accounts
  for the 2×-denser dots sampling.

Added

• TUI Fan row: each fan's RPM reading is prefixed with a braille-cascade spinner
  (⠋⠙⠹⠸⠼⠴⠦⠧⠇⠏) whose spin rate is proportional to RPM, driven by its own timer
  decoupled from the sampler poll cadence.

Docs

• docs/DESIGN-system.md: document the dense 2-samples-per-character braille
  rendering (§5.2), refresh the grid/stack/process TUI capture frames, and add
  §4.2.1 explaining why temperature is reported per-cluster (not per-core) —
  including the Apple Silicon sensor-count reality and how btop's per-core
  temperature column actually spreads a few cluster sensors across rows.
• Rename docs/DESIGN-sdlc-cicd-release.md → docs/DESIGN-sdlc-cicd.md
  ("release" is already implied by CI/CD) and update all references.

Tests

• tests/test_runtime_contracts.py: enforce the functional-tests-only mandate —
  remove test_soc_info_contract and test_top_processes_contract (pure
  shape/bounds assertions whose code paths are already covered behaviorally by
  test_config.py and test_per_process_power.py), and rewrite the RAM test
  into a native-parse sanity guard (the derived-field invariants it previously
  asserted were tautological; the load-bearing check is that the raw reading is
  physically sane).
