config check: validates UUID format, recognized methods, keyfile
consistency and existence. Reports all issues with alias context.
remove: deletes a device from config by alias. Inverse of add.
status: --mounted, --unlocked, --locked flags filter the device table.
Flags combine as OR.
mount/unlock: display which method succeeded and key slot used, e.g.
"(fido2, key slot 1)". cryptsetup Open now runs with -v and parses
"Key slot N unlocked" from stderr via io.MultiWriter.

Privileged unmount now does a best-effort rmdir on the mount point after
umount succeeds. Only removes empty directories; non-empty dirs and
errors are silently ignored.

New 'arca add <device>' subcommand detects a LUKS device via udisks2 and
appends it to the config with passphrase as default method. Supports
--alias/-a to override the generated name. Skips if UUID already
configured. Adds Config.Save() and Config.HasUUID() to config package.

Add -v/--verbose persistent flag that prints debug info to stderr:
D-Bus connection status, token plugin directory discovery, unlock method
sequencing with per-method success/failure, and full cryptsetup command
lines including LD_LIBRARY_PATH.

udisks2 connection and device listing errors now suggest checking the
service. Device-not-found errors suggest 'arca status' or 'arca init'.
Failed cryptsetup token unlock hints at missing FIDO2/TPM2 key.

mount now detects already-unlocked and already-mounted devices, returning
the existing mount point instead of failing. unmount handles already-locked
devices gracefully and skips unmount if not mounted before locking.
Adds IsMounted helper to udisks client. Updates PLAN.md with refined
v1.0.0 milestones.

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.
