refactor(landing-page): Move sections/ to widgets/ directory with WSA structure

[JeremyDev87]

Parent Issue

• refactor(landing-page): Migrate to WSA (Widget-Slot Architecture) #660 Migrate to WSA (Widget-Slot Architecture)

Task

Move 5 files from sections/ directory to widgets/ directory and restructure them to follow WSA Widget conventions.

TODO

• sections/Hero.tsx → widgets/Hero/index.tsx
• sections/BeforeAfter.tsx → widgets/BeforeAfter/index.tsx
• sections/Features.tsx → widgets/Features/index.tsx
• sections/SupportedTools.tsx → widgets/SupportedTools/index.tsx
• sections/CTAFooter.tsx → widgets/CTAFooter/index.tsx
• Delete sections/ directory
• Update all import paths (@/sections/ → @/widgets/)

WSA Widget Structure

widgets/[Name]/
├── index.tsx       # Widget Entry Point (Server Component)
├── ui/             # Client Components (if needed)
└── types.ts        # Widget-specific types (if needed)

Notes

• Hero already uses TerminalDemo (Client Component) → consider ui/ separation
• Others are pure Server Components, index.tsx only is sufficient
• Existing widgets/AgentsShowcase, widgets/QuickStart, widgets/TerminalDemo require no changes

Acceptance Criteria

• sections/ directory no longer exists
• All Widgets follow widgets/[Name]/index.tsx structure
• Typecheck passes after import path changes
• All existing tests pass
