ecosystem.deploy.config.cjs

/**
 * PM2 entry for the alpha auto-deploy poller. Kept out of ecosystem.config.cjs
 * on purpose:
 *
 *   - Releases run `pm2 start ecosystem.config.cjs` to (re)register the 13
 *     app processes. If the poller were in that file, a deploy would
 *     `pm2 delete` and restart the very process it is executing in.
 *   - The poller must run from ~/alpha (the object-store checkout), which
 *     `git fetch` keeps on origin/main, so scripts/deploy.sh updates itself.
 *     A release directory is frozen at one commit.
 *
 * Register once, on the box:
 *
 *   cd ~/alpha && pm2 start ecosystem.deploy.config.cjs && pm2 save
 *
 * All DEPLOY_* knobs are documented at the top of scripts/deploy.sh.
