Hash D Island 1.0.0

The first release. The notch becomes a living surface: quiet when nothing is
happening, alive the moment something is.

Now Playing for any app that publishes a track, a microphone-in-use indicator
that never listens, live internet speed, battery with adapter wattage and an
80% health cap it counts down to correctly, AirPods charge, real Apple Silicon
temperatures, processor and memory, storage, a timer, download notices, AI
token totals, and a local live-activity feed anything can post to.

Nothing leaves your Mac. One kind of network request exists — fetching a cover
from Spotify's or YouTube's image hosts — and nothing else in the app touches
the network. The island leaves the screen the moment the Mac locks. Switching
an indicator off stops it reading, not just showing.

Built for Apple Silicon, macOS 12 Monterey through macOS 26 Tahoe.
Released under the GNU General Public License v3.

  Idle cost measured on the packaged app, panel shut: 0.13-0.19% of one core
  and about two idle wake-ups a minute.

Distributed directly rather than through the Mac App Store, because reading
system-wide Now Playing and the real temperature sensors needs Apple interfaces
the store does not allow. The app is ad-hoc signed and not notarized, so the
first launch takes an extra step - the README explains it, including the
quarantine command for the case where macOS offers no button.
