3b961b5d8a Step 17: Encryption core — passphrase-only, selective per-file.
Manifest schema: Entry gains Encrypted, PlaintextHash fields.
Manifest gains Encryption section with KekSlots map (passphrase slot
with Argon2id params, salt, and wrapped DEK as base64).

garden/encrypt.go: EncryptInit (generate DEK, wrap with passphrase KEK),
UnlockDEK (derive KEK, unwrap), encryptBlob/decryptBlob using
XChaCha20-Poly1305 with random 24-byte nonces.

Modified operations:
- Add: optional encrypt flag, stores encrypted blob + plaintext_hash
- Checkpoint: detects changes via plaintext_hash, re-encrypts
- Restore: decrypts encrypted blobs before writing
- Diff: decrypts stored blob before comparing
- Status: compares against plaintext_hash for encrypted entries

10 tests covering init, persistence, unlock, add-encrypted, restore
round-trip, checkpoint, status, diff, requires-DEK guard.

d1a6e533a4 Step 8: Polish — lint, clock abstraction, e2e test.
- golangci-lint config with errcheck, govet, staticcheck, errorlint
- Fix all lint issues (unchecked error returns in cleanup paths, De Morgan)
- Inject jonboulle/clockwork into Garden for deterministic timestamps
- Add manifest.NewWithTime() for clock-aware initialization
- E2e lifecycle test: init → add → checkpoint → modify → status → restore → verify
- Update CLAUDE.md, PROJECT_PLAN.md, PROGRESS.md

Phase 1 (local) is now complete. All 9 CLI commands implemented and tested.

7a3d78d741 Step 2: Add manifest package with YAML data model and persistence.
Implements Manifest and Entry structs with YAML tags, New() constructor,
Load(path) for reading, and Save(path) with atomic write (temp file +
rename). Tests cover round-trip serialization, atomic save cleanup,
entry type invariants, nonexistent file error, and empty manifest.
