fix: point source refs at paths held at the pin

trident cites the Panda3DS fork 3dsTrident vendors as a submodule, now
its upstream at the submodule pin 69095ee6. pce-emu, uqm and stonesoup
wrote paths from a subdirectory (PCE.emu/, sc2/, crawl-ref/), nesoid
named two Java files without their directory; lines unchanged, each read
at the pin.

The pages no longer take a binary citation (DesktopKinect.dll, an
address continuing a BAM.dll range) for a source path, and a Forgejo
tree is read page by page: mirrors/Ryujinx holds 4704 entries, 1000 a
page.
