tauri-hasgard-cli 0.3.0

use assert_cmd::Command;

/// `tauri-hasgard --version` must print the CLI version. The flag was missing
/// entirely until issue #135 surfaced it (a caller couldn't tell which CLI
/// build they were running).
///
/// This doubles as the Windows stack-overflow guard. Building the clap command
/// tree overflowed the 1 MiB stack Windows gives a main thread, so every
/// invocation aborted with `STATUS_STACK_OVERFLOW` -- and `--version` is the
/// cheapest invocation there is, so a crash here means the binary is unusable
/// rather than that one flag is broken. It cannot fail on Linux or macOS, whose
/// 8 MiB main stacks were never close; only CI's Windows runner can see it.
