[FEAT] Activity feed — recent commits and PR events

[Priyanshu-byte-coder]

Summary

Add a chronological activity feed showing the user's most recent GitHub events (commits, PR opens/merges, issue closes).

What to build

• New API route: GET /api/activity
  • Fetch from GET /users/{login}/events?per_page=30
  • Filter to: PushEvent, PullRequestEvent, IssuesEvent
  • Map each to { type, repo, message, date, url }
• New component: src/components/ActivityFeed.tsx
  • Render a scrollable list (max height ~320px)
  • Each entry: icon (commit/PR/issue), repo name, short message, relative time (e.g. "2h ago")
  • Use date-fns/formatDistanceToNow (already a dependency)

Where to add

New row at the bottom of src/app/dashboard/page.tsx, full width.

Acceptance criteria

• Shows last 20 events
• Three event types with distinct icons
• Relative timestamps
• Links open in new tab
• Loading skeleton

Difficulty

Medium — straightforward API + list component.
