SolveCraft v0.2.1

This patch repairs common modelling workflows and feature dialog layout:

• Remove artificial thin wall strips created by Shell and extrusion cuts. Straight walls and rounded corners span their full height as physical faces, while authored face splits and face appearances remain protected. Permanent regressions cover material, reopening and unaffected bodies crossing the extrusion end plane.
• Opening feature dialogs or the command palette keeps Axis View and the navigation bar anchored to the viewport, including enlarged display scales. Covered controls remain protected against clicks through dialogs.
• Feature dialogs use available screen height, with OK and Cancel outside the scrolling fields.
• Sketch directly on eligible planar enclosure walls and shell floors after fillets, then cut a port and add mounting bosses. Attachments follow width and wall changes and survive reopening.
• Further fixes bound construction-plane traversal, sketch solving, control and file input, and STEP/IGES/3MF/DXF import work. Join merges all bodies the tool meets.
• CLI script result reporting now honors requested saves and exports and reports output failures. Coincident constraints between two distinct straight lines join their closest endpoints with deterministic pick-order ties.
• The README demo returns to the original enclosure workflow with an empty start, animated pointer, direct face sketches and comfortable framing.

Design files: older designs remain readable. Newly saved format 13 designs require SolveCraft 0.2.1 or later. Ambiguous or unsupported shell-face attachments still report an error rather than guessing a plane. References to a removed strip retain their saved projected geometry and report a lost reference; explicitly reselect the wall to repair that projection.

This is a patch release for repairs to the existing modelling workflow. Packages remain unsigned. The release assets include SHA256SUMS.txt; use it to verify your download.

Which file?

• Windows: SolveCraft-0.2.1-windows-x64.exe runs as is. Or install the .msi, or unzip the
  -portable.zip (x64, x86 and arm64).
• macOS 11+ (Apple silicon and Intel): open the .dmg and drag SolveCraft onto Applications.
  The CLI is in solvecraft-cli-0.2.1-macos-universal.zip.
• Linux (x86_64 and aarch64, glibc 2.35+): the .AppImage (chmod +x, then run it), the
  .deb or .rpm, the .flatpak (flatpak install --user <file>), or the .tar.gz.
• FreeBSD: tar -xzf solvecraft-0.2.1-freebsd-x86_64.tar.gz --strip-components 1 -C /usr/local.
• Web: solvecraft-web-0.2.1.zip is a static site to host yourself.
• SHA256SUMS.txt: sha256sum -c SHA256SUMS.txt --ignore-missing.

The builds aren't signed yet. On macOS, right-click SolveCraft in Applications and choose
Open the first time (or run xattr -dr com.apple.quarantine /Applications/SolveCraft.app).
On Windows, SmartScreen may say "Windows protected your PC": More info, then Run anyway.
Licences are built in (Help ▸ About ▸ Licences, solvecraft-cli licences); the packages also
install THIRD-PARTY-LICENSES.txt. Known limitations:
