* port color-eyre to new eyre with global hook * add a singular hook configuration * add panic handler to globally installed hook * getting near the end * remove unused module * temp: working on capture consistency * walk back changes that make porting to new release harder * merge main into hooked * switch to github color-spantrace and copy from htmlgit status * move spantrace capture default mode into hook * rename and reorg section stuff * switch to released deps * copy changes from lib.rs to readme * update snippets and revert to images for readme * remove extremely fragile format tests
