Routes with maxDuration=300 were silently failing on Vercel's edge
routing layer - requests never reached the serverless function (no
logs appeared). Vercel Hobby plan has a 60s max function duration.
Affected routes:
- /api/agents/[id]/conversation/[conversationId]
- /api/agents/[username]/[uid]/conversation/[conversationId]
- /api/mcp/[username]/[slug]/[transport]
The issue caused these routes to hang indefinitely until client timeout.
