Nocturne 1.5.0: lighter, measurably

Lighter, measurably

Nothing on screen changes. What changes is what Nocturne costs while it sits
there. Measured on macOS 26.6.2 against the shipped 1.4.1, same machine, same
settings (Only the clock, Hover to show on, shimmer Occasionally), each build
at steady state:

	1.4.1	now
CPU at rest, input idle	0.173%	0.042%
Wakeups at rest	3.71/s	1.00/s
CPU while the pointer moves (120Hz)	3.76%	0.60%

"At rest" counts only the seconds in which there was no keyboard or pointer
input at all, read from the HID idle timer, because a window with the owner
using the Mac folds pointer events into the number and flatters nobody.

Where it came from, largest first:

• The pointer. Hover to show watched every mouse move on every screen, and
  each one cost this process a wakeup to learn the pointer was still over a
  document. The monitor now naps for 150ms after any move that is nowhere near
  a bar, then looks once at where the pointer is. On a bar it stays awake, so
  leaving is seen at once. A listen-only event tap looked cheaper and is a
  trap: from an ad-hoc signed .app it is created without error and delivers
  0 of 2,099 events, because it needs Input Monitoring even for the mouse.
• The placement tick read the window list four times every 2s in Only the
  clock with Hover to show, all describing the same instant. It reads it once,
  lets the system fold the wakeup into one it was making anyway, and skips
  alpha writes that change nothing.
• The shimmer swept every 30s in Hide everything and Only the clock, where
  the strip covers the real icon and the visible one is a still copy on top.
  24 status item redraws per sweep, never seen. Those sweeps are skipped.
• Nobody watching, nothing running. With the displays asleep or the session
  switched away, the placement tick, the hover monitor and the shimmer stop,
  and catch up the moment a display wakes. The strip stays in place
  throughout. Screen lock is deliberately not a trigger: a missed "unlocked"
  would leave everything paused over a visible bar.
• The Focus backstop asked the system for the live Focus every 30s for the
  life of the app, including for everyone who never added the filter. It now
  runs only while a lost "Focus ended" would leave something wrong, and the
  suite proves over 50,000 random operations that outside that window a lost
  one changes nothing.
• Quitting no longer restarts Control Center when the clock is already
  digital, which in Only the clock and Clock visible it always is. That was a
  blank menu bar and a process relaunch at every quit and every logout.

Tests

106 checks, up from 103. The new ones pin the Focus backstop rule from both
sides and were validated by mutation: three deliberate defects in the rule,
all three caught.
