Address review notes on the refactor

Commit

- parseMappings returned a non-nil empty slice when no --map was given, where the old inline loops left Scope.Mappings nil; preserve nil so the request shape is unchanged.
- gitproto/convert.go no longer contained conversions after the dead PushPlan path was removed; rename it to readers.go to match its content (CloseOnce, LimitPackReader).
