Cursor Builds: pre-warmed environments boot cloud agents up to 3x faster

Cursor shipped Builds: environments prepared hourly in the background so cloud agents boot up to 3x faster. Broken builds never go active; the system falls back to the last good one. A new Builds tab in the dashboard shows logs and SHAs. It becomes the default for all environments on Aug 17 at no extra cost.

Warm environments remove the biggest latency tax on cloud coding agents. Once Builds is on by default for everyone on Aug 17, it becomes the baseline that competing products get benchmarked against.
