main.c was a single 6018-line translation unit. Cut it at the existing
section banners into ordered part files (state, draw, config, net, jpeg,
api, thumbs, display, ui, video, sync, app) that main.c #includes in
dependency order.
The parts form one translation unit and share all file-scope state, so
there are no headers, no extern decls, and no de-static-ing of the ~100
shared globals coupling the three threads. Only src/main.c is compiled
(CMakeLists unchanged). The slices are byte-exact: the preprocessed TU is
identical to the old main.c, so the binary is unchanged. Verified by a
clean build plus a Vita3K run (login, paging, grid, detail view, back nav,
no crash).
