Cost optimization insights

Every app has a Suggestions card on its overview tab listing cost-optimization and reliability ideas computed from traffic, crash, and deploy history. Four rule kinds:

• idle — zero requests + visitors in 30 days (app ≥14d old). Consider deleting.
• memory-pressure — 2+ OOM kills in 14 days. Upgrade plan or reduce memory use.
• overprovisioned — on maker/pro with <100 req/day average over 14 days and no OOMs. Consider downgrading.
• deploy-regression — 3+ failed deploys in 24h. Something changed; review the latest build log.

Each suggestion has a one-click action button in the dashboard — Manage subscription, Upgrade to maker, View crash details — so non-MCP users get the same shortcut an AI assistant does.

For AI assistants: percher_app_insights returns the same structured suggestions with a machine-readable actionHint naming the follow-up tool (percher_billing_portal, percher_billing_upgrade, etc.) so the assistant can hand you a one-click URL in the same response.
