The closed backend's storage rework scopes collab rooms/keys by team:
room ids are now <scopeId>:<projectId>:<docPath> (@pcbjam/shared bump).
The editor threads a scopeId prop parallel to projectId — ToolPage takes
it from the project DTO (falling back to "local" for scope-less
backends; Home/LibTool pages pass "local" explicitly) — through WasmTool
into the doc session, sheet-manager warm rooms, and cross-app presence.
