Motion on the board now means one thing: THIS IS MAKING SOUND. It used to mean
only "a DJF sits at its zero mark", because animated() hard-returned False for
every role but family_filter.

Three laws, all at bar rate (the slow breath, not the beat one):

  fx / fx2, every orbit   breathe whenever the knob is off zero
  level, d9-d12 only      breathe whenever the level is not off. Only those
                          four, because d1-d8 levels live on row D and FADERS
                          HAVE NO LEDS — painting them was already called a
                          no-op lie in paint_cell, and asking for it here would
                          have been the same lie one layer up
  boolean cells           dark until 127, breathing at 127

That last law needs to know what a control IS, so parse_kinds() reads it off
the track: a cc reached through `# effect (... "^NN" ...)` is a dial, a cc
reached through midiOn/midiOff is a switch. Tidal applies midiOn's function
while the CC reads high, so such a control is boolean however many steps the
hardware sends — and a ring fading up across a range the music ignores is a
ring that lies about the sound. When one cc is used both ways, continuous wins:
the value demonstrably matters somewhere, so fading is the honest paint.

The breath's CEILING is the value (_breathe_to): the brightest instant equals
_lightness(value) and never exceeds it, so "lightness carries VALUE" still
holds while motion carries engagement. A knob at 30% breathes dim.

Levels stay honest. Ardour owns cc 13-16 and has not told us their values, so
ring_colour(value_known=False) keeps the flat rest colour rather than breathing
on a guess — the oldest rule here is that the LEDs do not lie. The feedback
feed that fills ardour_seen comes next; until it does, those four rings look
exactly as they did.

Also folds two defaults that had drifted: paint used 0 for an unseen control
and the glow tick used 64. value_of() settles it — an unseen DJF is at its
centre detent, because that is where the knob physically rests; anything else
unseen is OFF, because engagement we have never observed must not be claimed.

Checked against rose_rouge: B8+C8 (d8's stacks, the ones asked about) classify
bool; A6/A7/A8's delay and squiz knobs classify cont; breath peak equals the
static value at every level; DJF behaviour unchanged; unmapped still black.
