Remove stale root-level files; make Sidebar self-contained via usePathname()

[Copilot]

18 duplicate/outdated files at the project root were polluting the TypeScript surface and creating confusion about which files are canonical. The Sidebar required every page to manually thread its own route path through AppShell down to the nav.

Changes

• Deleted 18 stale root-level files (sidebar.tsx, store.ts, validators.ts, demo-db.json, app-shell.tsx, etc.) — all older copies of files now living under components/, lib/, app/, and data/

• Sidebar → "use client" with usePathname() — active nav item is now derived from the live URL instead of a hardcoded prop:

// Before: every page had to declare its own route
<AppShell pathname="/dashboard" title="Dashboard" ...>

// After: Sidebar reads the route itself, no prop needed
<AppShell title="Dashboard" ...>

• Removed pathname prop from AppShell and all 11 page components
