fix(server): keep a new worktree open when its paseo.json cannot be parsed (#6036)

* fix(server): keep workspaces available after setup config errors

* refactor(server): drop the archive dependency from worktree setup

Setup no longer archives a workspace when it fails, so the setup
workflows no longer take archiveWorkspaceRecord.

* test(server): stop passing the removed archive dependency to the worktree workflow

* test(server): check paseo.json survives without comparing line endings

Git checks the fixture out with CRLF on Windows, so comparing its exact
contents failed there.
