Redesign both Issues and My Issues headers with Linear-style layout:
- Left: scope pill buttons (All/Members/Agents for Issues; Assigned/Created/My Agents for My Issues)
- Right: compact icon buttons for Filter, Display, and View toggle
- Selected scope has accent background, all buttons use consistent outline variant
- Filter active indicator uses brand-colored dot
- Tooltips on all buttons with 500ms global delay
- Remove New Issue button and issue count from headers
- Scope selection persisted to localStorage

Upgrade /my-issues from a simple accordion to a full-featured view
matching /issues — kanban board, list view, status/priority filtering,
sorting, and display settings, scoped to the user's own issues.
Key changes:
- Extract view store factory (createIssueViewStore) using zustand v5
vanilla createStore + React Context for shared component reuse
- Create ViewStoreProvider + useViewStore/useViewStoreApi hooks
- Decouple BoardView, BoardColumn, BoardCard, ListView from global
useIssueViewStore — they now read from context
- New independent persisted store for /my-issues (multica_my_issues_view)
- Simplified MyIssuesHeader (no assignee/creator filters)
- Pre-filter logic: assigned to me ∪ my agents ∪ created by me
- Generalize workspace sync to clear filters on all registered stores
- Fix existing debt: text-[10px] → text-xs, w-44 → w-auto, reduce
unnecessary selector subscriptions in both headers
