05 — UI/API Route Package (Track D)

All routes are view/function-backed pass-throughs (the established rpQuery pattern). No Nuxt math. Staged at /opt/incomex/docs/mcp-writes/rp-dynamic-drill-2026-06-05/ui-package/.

Existing routes preserved: node.get.ts, rows.get.ts, summary.get.ts (already PG pass-throughs).

Install/PR/rollback: see ui-package/INSTALL_AND_PR.md. Deploy is operator-gated (main cron-owned; feat divergent — no agent push).
