07400f2828 fix: skip target database check for cluster restores 
- Cluster restores restore multiple databases, not a single target
- Database existence check was failing with exit status 2
- Now shows "Will restore all databases from cluster backup" instead
- Removes confusing warning for cluster restore operations

87e0ca3b39 feat: implement full restore functionality with TUI integration 
- Add complete restore engine (internal/restore/)
  - RestoreSingle() for single database restore
  - RestoreCluster() for full cluster restore
  - Archive format detection (7 formats supported)
  - Safety validation (integrity, disk space, tools)
  - Streaming decompression with pigz support

- Add CLI restore commands (cmd/restore.go)
  - restore single: restore single database backup
  - restore cluster: restore full cluster backup
  - restore list: list available backup archives
  - Safety-first design: dry-run by default, --confirm required

- Add TUI restore integration (internal/tui/)
  - Archive browser: browse and select backups
  - Restore preview: safety checks and confirmation
  - Restore execution: real-time progress tracking
  - Backup manager: comprehensive archive management

- Features:
  - Format auto-detection (.dump, .dump.gz, .sql, .sql.gz, .tar.gz)
  - Archive validation before restore
  - Disk space verification
  - Tool availability checks
  - Target database configuration
  - Clean-first and create-if-missing options
  - Parallel decompression support
  - Progress tracking with phases

Phase 1 (Core Functionality) complete and tested
