TASK-242	Fix stats server Bun fallback in coverage lane	In Progress		2026-03-29 07:31	ci bug	cleanup		PR #36	high

Description

Coverage CI fails when startStatsServer reaches the Bun server seam under the maintained source lane. Add a runtime fallback that works when Bun.serve is unavailable and keep the stats-server startup path testable.

Acceptance Criteria

• #1 bun run test:coverage:src passes in GitHub CI
• #2 startStatsServer uses Bun.serve when present and a Node server fallback otherwise
• #3 Regression coverage exists for the fallback startup path
