ci: add Presto healthcheck to docker-compose

[dtsong]

Problem

Presto service in docker-compose.yml (lines 93-105) has no healthcheck. The --wait flag returns immediately, meaning tests can hit Presto before the JVM coordinator finishes startup, causing flaky CI.

Fix

Add healthcheck using Presto's /v1/info endpoint:

healthcheck:
  test: ["CMD", "curl", "-f", "http://localhost:8080/v1/info"]
  interval: 10s
  timeout: 5s
  retries: 12
  start_period: 30s

Acceptance Criteria

• Presto service has healthcheck in docker-compose.yml
• make up-full waits for Presto to be ready before returning
