feat(restore): add weighted progress, pre-extraction disk check, parallel-dbs flag 
Three high-value improvements for cluster restore:

1. Weighted progress by database size
   - Progress now shows percentage by data volume, not just count
   - Phase 3/3: Databases (2/7) - 45.2% by size
   - Gives more accurate ETA for clusters with varied DB sizes

2. Pre-extraction disk space check
   - Checks workdir has 3x archive size before extraction
   - Prevents partial extraction failures when disk fills mid-way
   - Clear error message with required vs available GB

3. --parallel-dbs flag for concurrent restores
   - dbbackup restore cluster archive.tar.gz --parallel-dbs=4
   - Overrides CLUSTER_PARALLELISM config setting
   - Set to 1 for sequential restore (safest for large objects)

Usage

  1. Download the appropriate binary for your platform
  2. Make it executable (Unix-like systems): chmod +x dbbackup_*
  3. Run: ./dbbackup_* --help

Interactive Mode

Launch the interactive TUI menu for easy configuration and operation:

# Interactive mode with TUI menu
./dbbackup_linux_amd64

# Features:
# - Interactive configuration settings
# - Real-time progress display
# - Operation history and status
# - CPU detection and optimization

Command Line Mode

Direct command line usage with line-by-line progress:

# Show CPU information and optimization settings
./dbbackup_linux_amd64 cpu

# Auto-optimize for your hardware
./dbbackup_linux_amd64 backup cluster --auto-detect-cores

# Manual CPU configuration  
./dbbackup_linux_amd64 backup single mydb --jobs 8 --dump-jobs 4

# Line-by-line progress output
./dbbackup_linux_amd64 backup cluster --progress-type line

CPU Detection

All binaries include advanced CPU detection capabilities:

  • Automatic core detection for optimal parallelism
  • Support for different workload types (CPU-intensive, I/O-intensive, balanced)
  • Platform-specific optimizations for Linux, macOS, and Windows
  • Interactive CPU configuration in TUI mode
