…on git logic into separate file, add new `verbose-logging` option for message logging, add new output channel for dedicated log output now we don't ship our own file exclude handling anymore (constraint e.g. by nesting depth) and instead just ask VSCode directly for the list of repositories the user has opened. This means that said list now also updates automatically on change as you'd expect. removes the need for `glob` package, reducing bundle size significantly fixes detection of working tree changes or head moves e.g. on `commit --amend` (#9) closes #9
