Implement NavigationProvider with stack-based screen routing and context
Create the NavigationProvider that manages the screen navigation stack consumed by the ScreenRouter, HeaderBar breadcrumbs, and all go-to/deep-link features. (1) providers/NavigationProvider.tsx: React context providing push(screen, params), pop(), replace(screen, params), reset(screen, params), canPop(), stack (read-only), current (top of stack). (2) router/types.ts: ScreenEntry type { id: string, params?: Record<string, string> }, NavigationContextType interface. (3) Stack model: array of ScreenEntry, max depth 32, oldest entry dropped on overflow, push deduplicates consecutive identical screens. (4) push() adds to stack, pop() removes top (no-op on root), replace() swaps top, reset() clears to single entry. (5) useNavigation() consumer hook. (6) Stack is not persisted across TUI restarts. (7) All operations are synchronous and trigger re-render.
