[scanner] Split src/app/[locale]/marketplace/page.tsx (742 lines) — extract InstallModal and MarketplaceCard

[hivecommons-hive]

Problem

src/app/[locale]/marketplace/page.tsx is 742 lines and bundles three distinct components plus shared types/constants in one file:

• InstallModal (lines ~99–330, ~230 lines): console-detection state machine (ConsoleStatus), install flow, clipboard/terminal instructions
• MarketplacePage (lines ~331–632): registry fetch, search/filter/sort state, layout
• MarketplaceCard (lines ~633–742): per-item card rendering
• Shared: MarketplaceItem/RegistryData interfaces, TYPE_CONFIG, REGISTRY_URL, console-detect constants

Proposed split

src/app/[locale]/marketplace/
  page.tsx              # MarketplacePage only (~300 lines)
  components/InstallModal.tsx
  components/MarketplaceCard.tsx
  lib/types.ts          # MarketplaceItem, RegistryData, ConsoleStatus
  lib/constants.ts      # TYPE_CONFIG, REGISTRY_URL, CONSOLE_* constants

Acceptance criteria

• No behavior change; page renders identically
• Each new file < 350 lines
• npm run build and npm run lint pass
