epriestley 0b3cd39230 Update the "WorkingCopy" API and create a fallback "Filesystem" working copy ... Summary: Ref T11968. - Allow "WorkingCopy" objects to maintain an API object and update callers ("get...()" instead of "new...()"). - Always generate a WorkingCopy object and a RepositoryAPI object. Currently, code has to look like this: ``` $working_copy = ... if ($working_copy) { $repository_api = ... if ($repository_api [instanceof ... ]) { ``` This is clunky. There's also no reason some "arc" commands can't run outside a VCS working directory without special-casing how they interact with the filesystem. Conceptually, model the filesystem as a trivial VCS (which stores exactly one commit, always amends onto it, and discards history). Provide a trivial WorkingCopy and API for it. (This change isn't terribly interesting on its own, but chips away at landing the new Hardpoint infrastructure.) Test Plan: Ran `arc version`, `arc upgrade`.
