/**
* Workspace HTTP effects — the injected edge that talks to the backend's
* workspace endpoints. Mirrors the store's fetch pattern: `httpBase` + an
* injected `fetchImpl` (so it is testable without the network). Returns typed
* `WorkspaceResult<T>` (`{ok,value}` | `{ok:false,error}`) for mutating ops so a
* caller can surface the backend's `{ error }` reason; reads return data or a
* safe empty/null on failure (non-fatal — the UI falls back gracefully).
*
* Endpoints ([email protected]):
* - `GET /workspaces` → list
* - `PUT /workspaces/:id` (create-on-miss, idempotent) → ensure
* - `GET /workspaces/:id` (404 → null) → get
* - `PUT /workspaces/:id/title` → rename
* - `PUT /workspaces/:id/default-cwd` → set/clear default cwd
* - `PUT /workspaces/:id/default-computer` → set/clear default computer (SSH handoff #2)
* - `DELETE /workspaces/:id` (409 for "default") → delete
