Note

Medium Risk
Split deployments depend on exactly one controller per database and correct SERVER_URL; misconfiguration could duplicate dispatch or leave schedules idle, and Helm value renames (replicaCount → server.replicaCount) are a breaking chart upgrade.

Overview
Adds dist/controller-main.js so schedule dispatch and other periodic control loops can run as a single-replica process in distributed mode (STANDALONE=false), calling the server API over HTTP via new SERVER_URL (default http://localhost:$PORT). Standalone still runs the controller in the server process; the dedicated entry exits cleanly when STANDALONE=true.

Build & dev: tsup emits controller-main; package scripts add start:controller and parallel dev:controller for local split-process dev. Logs gain a component field (server | controller) in JSON mode.

Deployments: Docker Compose, Railway IaC, and the Helm chart each gain a second controller workload (fixed 1 replica, Recreate / zero overlap on Railway) with SERVER_URL pointed at the server service. Helm moves server scaling knobs under server.replicaCount / server.strategy and documents the controller Deployment (no Service, distinct selector labels so traffic never hits controller pods).
