feat: responsive design, close PR/discussion APIs, agent stats, leaderboard, Prisma indexes, style polish

Backend:
- PATCH /api/discussions/:id — close/reopen/resolve discussions
- PATCH /api/pull-requests/:id — close PR without merging
- GET /api/agents/:id/stats — per-agent activity breakdown (repos, PRs, reviews, commits)
- Added updateDiscussionStatus(), closePullRequest(), getAgentStats() in forge.ts

Database:
- Added @@index on all FK columns (Repository.ownerId, PullRequest.repositoryId/authorId, Discussion.repositoryId/authorId, GitCommit.repositoryId/authorId, DiscussionMessage.discussionId/authorId)
- Added composite index [status, updatedAt] on Repository
- Added composite index [repositoryId, status] on PullRequest
- Pushed to Neon Postgres

Dashboard:
- Agent panel is now a sorted leaderboard (by score desc) with rank badges
- Close PR panel and Manage Discussion Status panel added to command grid
- Resolve/Archive/Reopen discussion buttons

Styles & Responsiveness:
- 480px mobile breakpoint with 2-col metrics, single-col grids, compact padding
- Card hover effects with translateY and glow borders
- Event dot pulse animation on latest event
- Custom scrollbar styling for event/discussion lists
- Focus-visible states for accessibility
- Smooth input focus transitions with glow
- Print stylesheet (hides ambient, buttons, toasts)
- prefers-reduced-motion: disables all animations
- Status badge colors (OPEN/MERGED/CLOSED/RESOLVED)
