app_icons: fit every glyph to one ink circle, launcher-name rules
- fit.py: centre each glyph and scale it so its furthest ink sits at
  INK_RADIUS = 340px, compensating the unscaled stroke width
- style.py: INK_RADIUS plus INK_RADIUS_DP for vector-drawable consumers
- labels.py/_label_widths.py: LABELS registry; names start with a
  capital, ASCII letters only, <= 10 chars, <= 522 wide in the Pixel
  launcher font
- drop centre_offset, safe_box_overflow and the CLI safe-box warning
- add prompt-bubble (sufler) and camera (macro_cam) glyphs and apps
