Smart-cube timing, macOS Bluetooth, Android app, stackmat, pairing UI

- Timing with a smart cube: the scramble stays put and is marked off
  move by move (ScrambleTracker); a stray turn gets the shortest path
  to the same scrambled state from the two-phase solver, kept until
  the next stray turn. Wide moves in BLD scrambles become face turns.
  Once scrambled, inspection (or blind memo) starts by itself after a
  configurable delay; the first turn starts the clock and the solved
  cube stops it. The cube's own state reports are authoritative, so a
  move lost over Bluetooth can't keep the timer running. Blind solves
  show a MEMO/EXEC annunciator and store the memo split. A live view
  of the cube sits beside the timer.
- Bluetooth through Kable on macOS and Windows (Linux keeps BlueZ) and
  on Android; the cube's MAC is read from its advertisement where the
  platform hides it. Scan/pair/connect/forget UI in settings.
- Android app (:android): core and ui gain Android targets, with a
  jvmShared source set for code desktop and Android share. Android
  host for storage, sound, file import, images, Bluetooth and audio.
  Phone layouts: stacked panes and a full-screen timer with touch
  start. Scramble drawings (SVG) are desktop-only for now.
- Stackmat: audio decoder and session; the mat can drive the timer.
- Timer readout always shows the tens-of-seconds digit.
- UI copy reduced to plain labels; marquee, snow, pointer-following
  and penguin speech removed. Brave key can be entered in settings.
- Phone timer: one-line header, session picker and averages on one
  line, solves/stats in the footer; sessions can be renamed and
  deleted and are named <event>-<date>. Display mode fills the screen
  (cut-out included), fits the scramble on one line, shows the live
  cube, and the screen stays awake.
- Readout: digits keep one size (inspection included), whole seconds
  while running unless set otherwise; previous scramble shown; the
  scramble no longer blanks while the next is generated.
- Fixes: stackmat and smart cube no longer both drive the timer; a
  solved cube or a sub-quarter-second tap can't record a solve.
- Blind memo indicator is an LCD penguin pacing the glass.
- Android: system-bar insets, folder picker (all files access), Brave
  key synced with the data.
- Algorithm trainer: PLL and OLL from J Perm's sheets, each algorithm
  verified by simulation; case plans, your choice of algorithm (or
  your own, checked against the case), new/learning/known, and a
  drill weighted towards weak cases.
- Pair cards show the pair on a 3D see-through cube with an arrow;
  the memo cube can be dragged between targets.
- CI image installs the Android SDK and runs core tests + desktop
  packaging (untested).
