Readiness probe

Unauthenticated **readiness** check (`GET /v1/ready`) — the deep sibling of `/health`, not a replacement for it. Where `/health` reports only that the process is serving, this one verifies the dependency every other endpoint needs. It pings the database inside a short timeout, then answers `503` (`status: degraded`) when it is unreachable and `200` (`status: ok`) otherwise. Use `/health` to ask "is the process alive?" (liveness — e.g. a restart decision) and `/ready` to ask "can it actually serve?" (readiness — e.g. load-balancer rotation or an uptime monitor). It requires no credential and returns no tenant data, but it is rate-limited per source IP, so poll it on the order of once a minute rather than continuously.

curl -X GET "https://example.com/ready"
