Idle previews go to sleep and wake on the next request, and Compose services start beside the app, one stack per branch.

• 6f4fa67feat:

  Idle previews sleep after sleep_after and wake on the next request in about two seconds

  A sleeping preview keeps its snapshot and data but uses no compute. The default is 30m; set sleep_after = "never" to keep one awake.

• aa612acfeat:

  Compose support: services in compose.yaml start beside the app, one stack per branch

  Burrow reads the services you already have. Ports are rewired so two branches never collide.

• 699a981perf:

  The build cache restores in parallel; warm builds are 34% faster on a typical Next.js app

• b05963bfix:

  Health checks follow redirects before deciding whether a preview is up
