ShapeCraft 0.5.0-alpha

New:

• The first launch asks a second question after the device: which app's navigation feels like home. Your existing
  install asks it once too. All twelve navigation presets now fit in the Navigation Presets window (the last three
  were cut off).

Fixed:

• A cut made from a plane that isn't on a body goes into the bodies it really runs into. It used to cut the oldest
  body whose bounding box it touched, so a logo pushed into an inset panel cut the shell around it instead.

For scripts and agents:

• sketch returns its plane (origin, u and v axes, normal) and takes x_dir to aim the u axis.
• inspect gives each region its hole count and the region it sits inside (letters' counters, nested rings), and
  narrows to one body or sketch, with faces: false to leave out face lists.
• "look": false keeps the open app's camera still when a script starts a sketch. visual_settings says that
  environments show in Visualize.
• docs/mcp.md: a one-line setup for agent tools, the sketch axis table, and conventions that used to need testing.

Alpha: keep copies of anything important. ShapeCraft updates itself from here on: it downloads new
versions in the background and installs them when you close it.

First launch: macOS asks once: System Settings ▸ Privacy & Security ▸ Open Anyway.
Windows SmartScreen: More info ▸ Run anyway. Linux: make the AppImage executable, then double-click it.

Check a download against SHA256SUMS.txt: shasum -a 256 FILE (macOS, Linux) or Get-FileHash FILE (Windows).
