replace localStorage context with zustand persist store
Optimization #10:
- created useSettingsStore with zustand persist middleware
- removed SettingsContext.tsx (88 lines) and provider wrapper
- added SSR-safe storage with cross-tab synchronization
- automatic JSON serialization, no manual parse/stringify
- maintained backward-compatible API (useSettings hook)
- bundle size: +2.3KB for zustand library
