0.2.39 compatibility repair pass
- DBW remains DBW when DBW is installed; legacy DBW blocks convert to DBS only when DBS is the target.
- Captures/restores server-authoritative DBW and DBS networks without Photomancy.
- Supports stationary/static endpoints as well as Sable sublevel endpoints.
- Preserves DBW Typewriter block and wire channels; converts standard legacy Typewriter channels when migrating to DBS.
- Captures, sanitizes, and remaps Simulated swivel-bearing references/constraints; understands legacy Photomancy bearing sidecars.
- Explicitly cancels new sublevel linear/angular velocity after reconstruction.
- Schematicannon visual reflection now tolerates missing optional API classes (e.g. ComputerCraft).
- Structure-only build files use .nbt; .sable_build.nbt remains for captures containing Sable ships.
