Plan 19-02 Summary: InboxList and MessageCard Components

What was built

Created the two core list-view components for the agent inbox:

1. MessageCard (packages/web/src/components/MessageCard.tsx) — Individual message row showing:

   • Status indicator: filled circle (requires response) vs empty circle (informational)
   • Agent name with parenthesized status label (e.g., "gastown (waiting for input)")
   • Message preview truncated to 80 chars with ellipsis
   • Relative timestamp via inline formatRelativeTime helper
   • Selected state with accent background

2. InboxList (packages/web/src/components/InboxList.tsx) — Container list component providing:

   • Header with "Agent Inbox" title, count badge, and Refresh button
   • Filter buttons: All / Waiting / Completed
   • Sort buttons: Newest / Oldest
   • Agent-message joining (matches message.senderId to agent.id, picks latest)
   • Empty state: "No pending messages" with subtitle

Decisions

• 19-02: Inline formatRelativeTime helper in MessageCard (no separate utils file per plan spec)
• 19-02: Filter/sort as button groups (not dropdowns) for simplicity per plan spec
• 19-02: Count badge shows total joined entries (not filtered count) to match wireframe "Agent Inbox (3)"
• 19-02: cn() import from @/lib/utils for className merging (consistent with all other components)

Verification

• npx tsc --noEmit -p packages/web/tsconfig.app.json — passes (exit 0)
• npx vite build — passes (exit 0, 520 kB bundle)
