c620860de3 feat: Phase 4 Tasks 3-4 - CLI encryption integration 
Integrated encryption into backup workflow:

cmd/encryption.go:
- loadEncryptionKey() - loads from file or env var
- Supports base64-encoded keys (32 bytes)
- Supports raw 32-byte keys
- Supports passphrases (PBKDF2 derivation)
- Priority: --encryption-key-file > DBBACKUP_ENCRYPTION_KEY

cmd/backup_impl.go:
- encryptLatestBackup() - finds and encrypts single backups
- encryptLatestClusterBackup() - encrypts cluster backups
- findLatestBackup() - locates most recent backup file
- findLatestClusterBackup() - locates cluster backup
- Encryption applied after successful backup
- Integrated into all backup modes (cluster, single, sample)

internal/backup/encryption.go:
- EncryptBackupFile() - encrypts backup in-place
- DecryptBackupFile() - decrypts to new file
- IsBackupEncrypted() - checks metadata/file format
- Updates .meta.json with encryption info
- Replaces original with encrypted version

internal/metadata/metadata.go:
- Added Encrypted bool field
- Added EncryptionAlgorithm string field
- Tracks encryption status in backup metadata

internal/metadata/save.go:
- Helper to save BackupMetadata to .meta.json

tests/encryption_smoke_test.sh:
- Basic smoke test for encryption/decryption
- Verifies data integrity
- Tests with env var key source

CLI Flags (already existed):
--encrypt                      Enable encryption
--encryption-key-file PATH     Key file path
--encryption-key-env VAR       Env var name (default: DBBACKUP_ENCRYPTION_KEY)

Usage Examples:
  # Encrypt with key file
  ./dbbackup backup single mydb --encrypt --encryption-key-file /path/to/key

  # Encrypt with env var
  export DBBACKUP_ENCRYPTION_KEY="base64_encoded_key"
  ./dbbackup backup single mydb --encrypt

  # Cluster backup with encryption
  ./dbbackup backup cluster --encrypt --encryption-key-file key.txt

Features:
✅ Post-backup encryption (doesn't slow down backup itself)
✅ In-place encryption (overwrites original)
✅ Metadata tracking (encrypted flag)
✅ Multiple key sources (file/env/passphrase)
✅ Base64 and raw key support
✅ PBKDF2 for passphrases
✅ Automatic latest backup detection
✅ Works with all backup modes

Status: ENCRYPTION FULLY INTEGRATED ✅
Next: Task 5 - Restore decryption integration

e059cc2e3a feat: Step 4 - Add --backup-type incremental CLI flag (scaffolding) 
Added CLI integration for incremental backups:

cmd/backup.go:
- Added --backup-type flag (full/incremental)
- Added --base-backup flag for specifying base backup
- Updated help text with incremental examples
- Global vars to avoid initialization cycle

cmd/backup_impl.go:
- Validation: incremental requires PostgreSQL
- Validation: incremental requires --base-backup
- Validation: base backup file must exist
- Logging: backup_type added to log output
- Fallback: warns and does full backup for now

Status: CLI READY but not functional
- Flag parsing works
- Validation works
- Warns user that incremental is not implemented yet
- Falls back to full backup

Next: Implement CreateIncrementalBackup() and RestoreIncremental()

1e73c29e37 fix: Ensure CLI flags have priority over config file 
- CLI flags were being overwritten by .dbbackup.conf values
- Implemented flag tracking using cmd.Flags().Visit()
- Explicit flags now preserved after config loading

eb3e5c0135 Fix: MySQL/MariaDB socket authentication - remove hardcoded -h flag for localhost 
Issue: MySQL/MariaDB functions always used '-h hostname' flag, which can cause
issues with Unix socket authentication when connecting to localhost.

Similar to PostgreSQL peer authentication, MySQL prefers Unix socket connections
for localhost rather than TCP connections. Using '-h localhost' forces TCP which
may fail with socket-based authentication configurations.

Fixed locations:
1. internal/restore/safety.go:
   - checkMySQLDatabaseExists() - now conditionally adds -h flag
   - listMySQLUserDatabases() - now conditionally adds -h flag

2. cmd/placeholder.go:
   - mysqlRestoreCommand() - now conditionally adds -h flag

Pattern applied (consistent with PostgreSQL fixes):
- Skip -h flag when host is localhost, 127.0.0.1, or empty
- Only add -h flag for actual remote hosts
- Allows mysql client to use Unix socket connection for local access

This ensures MySQL/MariaDB operations work correctly with both:
- Socket authentication (localhost via Unix socket)
- Password authentication (remote hosts via TCP)
