/**
 * Returns true when the current process looks like it's being driven by a
 * coding agent, CI runner, test runner, or anything else that won't render an
 * interactive TUI / prompt well.
 *
 * Two callers rely on this:
 *  - `Cli/selectCli.ts` uses it to pick `LoggingCli` over the Ink TUI.
 *  - `Auth/Profile.ts` uses it to refuse to launch an interactive credential
 *    configure flow (and thus avoid acquiring an auth lockfile) when there's
 *    no TTY to drive the prompts.
 *
 * Kept in `Util` (rather than `Cli`) so `Auth` can depend on it without
 * pulling in the CLI layer.
