Subject: [PATCH] feat(daemon): Add binary age detection to status command
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Shows binary modification time in gt daemon status and warns when
the binary is newer than the running process, suggesting a restart.
This helps detect when bug fixes or new features aren't active because
the daemon is running old code.
