* MUL-2216: feat(agents,squads): persist Mine/All tab selection per workspace
Tab selection on the Agents and Squads list pages was held in
component-local state, so navigating into a detail page and back
remounted the list and reset the tab to the default "Mine". Move
`scope` into Zustand stores backed by `persist` +
`createWorkspaceAwareStorage`, matching the pattern used by the
Issues view store. Selection now survives list → detail → back
navigation and page reloads, scoped per workspace.
Only `scope` is persisted; `search`, `sort`, and other ephemeral
filters intentionally still reset on remount.

* fix(views): reset scope to mine when switching to a workspace with no persisted value
zustand persist.rehydrate() is a no-op when storage returns null, so
workspaces with no entry kept the previous workspace's in-memory scope
("all" leaked from one workspace into the next). Provide a custom merge
that resets to the default "mine" when no persisted state is present.
Add coverage for the missing-storage workspace-switch case for both
Agents and Squads.
