When developing multiple addons, a stale or unreachable symlink from another addon could cause startup to fail. Because handle_fatal_error() called sys.exit(1) and launch.py silently ignored SystemExit, Blender would just close without any clue about what went wrong — making it very hard to diagnose. Replace sys.exit(1) with raise RuntimeError(message) so the error propagates to launch.py's except block, which now unconditionally prints the traceback. This keeps Blender running and gives the user a clear error message pointing to the problematic addon. The SystemExit special-case in launch.py is removed since handle_fatal_error no longer calls sys.exit.
Add .claude and .vscode to .gitignore and fix missing newline at EOF. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
