rig-build: -j12, and a deps image that has wxInspector

Browse Source 
Raises the bound from -j8 to -j12: the incident dump measured 1.17 GB average per cc1plus,
so 12 in flight is ~14 GB typical, well inside the 40 GB cgroup ceiling that is the real
guarantee. Keeps the file byte-identical to snaporca's copy, which the header requires.

Dockerfile.deps builds the deps with -j 12 for the same reason, and symlinks
deps/build/destdir -> deps/build/OrcaSlicer_dep: this tree installs under the latter name
while the orcacad_buildcache volume has the former baked as absolute paths in its CMakeCache.
Same tree, two names — without the link, one directory rename costs a full cold rebuild.
