Every tests/*.rs file is its own executable that links the whole crate graph. Move each crate's test files into tests/it/ as modules of one tests/it/main.rs; helper modules under tests/common move with them. These keep their own binary (own process): - engine panic_hunt: a process-wide panic hook counts every panic. - engine text_gamma: changes the process-wide text gamma. - engine smart_filter_stages, mask_cache_purge: assert on global caches. - codecs pnm_peak_memory: reads the process's peak RSS. - photocraft mac_menu_appkit: harness = false.
