// Regression tests for getWorkspaceInfo's 410-handling — pinned via
// the formatRemovedWorkspaceError pure helper so the test doesn't
// need to mock fetch + resolveWatching just to read one string.
//
// molecule-core#2429 — without these tests, the "your workspace was
// deleted, re-onboard" message is a 4-line code path that an
// inattentive refactor could collapse back into the generic
// "HTTP 410" error we used to surface.
