Locked files (--lock): repo-authoritative entries. Checkpoint skips
them (preserves repo version). Status reports "drifted" instead of
"modified". Restore always overwrites if hash differs, no prompt.
Use case: system-managed files the OS overwrites.
Directory-only entries (--dir): track directory itself without
recursing. Restore ensures directory exists with correct permissions.
Use case: directories that must exist but contents are managed
elsewhere.
Add refactored to use AddOptions struct (Encrypt, Lock, DirOnly)
instead of variadic bools.
Proto: ManifestEntry gains locked field. convert.go updated.
7 new tests. ARCHITECTURE.md and README.md updated.

CLI: sgard encrypt init [--fido2], add-fido2 [--label], remove-slot,
list-slots, change-passphrase. sgard add --encrypt flag with
passphrase prompt for DEK unlock.
Garden: RemoveSlot (refuses last slot), ListSlots, ChangePassphrase
(re-wraps DEK with new passphrase, fresh salt).
Proto: ManifestEntry gains encrypted + plaintext_hash fields. New
KekSlot and Encryption messages. Manifest gains encryption field.
server/convert.go: full round-trip conversion for encryption section
including KekSlot map.

Replace per-call SSH signing with a two-layer auth system:
Server: AuthInterceptor verifies JWT tokens (HMAC-SHA256 signed with
repo-local jwt.key). Authenticate RPC accepts SSH-signed challenges
and issues 30-day JWTs. Expired-but-valid tokens return a
ReauthChallenge in error details (server-provided nonce for fast
re-auth). Authenticate RPC is exempt from token requirement.
Client: TokenCredentials replaces SSHCredentials as the primary
PerRPCCredentials. NewWithAuth creates clients with auto-renewal —
EnsureAuth obtains initial token, retryOnAuth catches Unauthenticated
errors and re-authenticates transparently. Token cached at
$XDG_STATE_HOME/sgard/token (0600).
CLI: dialRemote() helper handles token loading, connection setup,
and initial auth. Push/pull/prune commands simplified to use it.
Proto: Added Authenticate RPC, AuthenticateRequest/Response,
ReauthChallenge messages.
