Go CLI using cobra with mount, unmount, status, and init subcommands. Unlocks via udisks2 D-Bus (passphrase/keyfile) or cryptsetup (FIDO2/TPM2) with ordered method fallback. Includes NixOS-specific LD_LIBRARY_PATH injection for systemd cryptsetup token plugins. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
