feat(ui): complete shell layout components (bb-ui2.6, .7, .8, .9, .27)

STORY:
Phase 1 of the Unified UX epic required a complete 3-panel shell layout
with responsive behavior across mobile, tablet, and desktop breakpoints.
The existing page structure was fragmented - we needed a cohesive shell.

COLLABORATION:
Three agents (bb-5am, bb-dwz, bb-3dv) worked in parallel on:
- TopBar: View tabs (Social/Graph/Swarm) with active states, filter input
- LeftPanel: Channel tree navigation with epic filtering, responsive collapse
- RightPanel: Detail strip with sidebar (desktop) / drawer (tablet/mobile) modes

We encountered a hydration mismatch error on mobile/tablet because
useResponsive was returning different values on server vs client.
Fixed by defaulting to desktop on server and only updating after mount.

Mobile navigation (bb-ui2.27) added:
- Hamburger menu for left panel access on mobile/tablet
- Bottom tab bar for thumb-friendly view switching

DELIVERABLES:
- src/components/shared/top-bar.tsx: TopBar with view tabs + hamburger
- src/components/shared/left-panel.tsx: Epic tree with expand/collapse
- src/components/shared/right-panel.tsx: Responsive sidebar/drawer
- src/components/shared/unified-shell.tsx: Main 3-panel grid layout
- src/components/shared/mobile-nav.tsx: Bottom tab bar for mobile
- src/hooks/use-responsive.ts: Breakpoint detection (mobile/tablet/desktop)
- Tests for all components

VERIFICATION:
- npm run typecheck: PASS
- npm run lint: PASS
- npm run test: PASS

CLOSES: bb-ui2.6, bb-ui2.7, bb-ui2.8, bb-ui2.9, bb-ui2.27
