v0.4.0 — Email Gate + Subscribe + Simplified Templates

What's New

Email Collection & Decision Tracking

• POST /api/subscribe — collect emails linked to idea checks via idea_hash
• GET /api/subscribers/count — subscriber metrics
• Dual-write: SQLite + stdout logging (Render logs survive redeploys)
• Email gate UI on mnemox.ai/check — pivot hints blurred until email provided

Simplified Agent Templates (Community Feedback)

• All templates reduced to one-line hints — MCP tool description handles the rest
• Agent auto-trigger is now optional, not primary
• CI section updated to use idea-check-action

Score History

• GET /api/history/{idea_hash} — retrieve past scores for an idea
• /api/check now returns idea_hash in every response
