Subject: [PATCH] fix(dev): clone mock IPC results to match real invoke
 semantics

Mock handlers return references straight into the in-memory db (e.g.
`return db.albums`), so store updates like set({ albums }) kept the same
array identity across loads and Zustand never notified subscribers --
the sidebar album list froze after creating an album from the bulk bar.
Real invoke() deserializes fresh JSON per call, so production was never
affected. structuredClone in the shim restores that fidelity for every
mock command at once.
