// LaunchPing — one anonymous "MacPal opened" count per launch.
//
// POSTs {app: "macpal", version, platform: "mac", install, fresh} to
// https://aesthetic.computer/api/app-open. `install` is a random UUID minted
// on first launch and kept in UserDefaults (not the Keychain) on purpose, so
// it goes when the app's data does; `fresh` is true only on that launch.
// Nothing here identifies the person: no account, handle, device, name or
// address rides along (see toolchain/analytics/VISITS.md).
//
// Fire-and-forget: no retries, errors swallowed, 10s ceiling, ephemeral
// session. Skipped in DEBUG builds, and when the `acLaunchPingDisabled`
// default is set:  defaults write <bundle id> acLaunchPingDisabled -bool YES
