A robust bash script to recursively clean Cargo projects, with special handling for workspace dependencies and missing files.

• Recursive Cleaning: Automatically finds and cleans all Cargo projects in subdirectories
• Workspace Support: Special handling for Cargo workspaces with dependency validation
• Missing File Handling: Gracefully handles missing dependency files in workspaces
• Multiple Fallback Methods: Uses various cleaning strategies when standard cargo clean fails
• Detailed Logging: Color-coded output with informative messages
• Error Recovery: Continues cleaning other projects even if some fail

# Clean all Cargo projects in current directory
./cargo-clean-recursive.sh

# Clean all Cargo projects in a specific directory
./cargo-clean-recursive.sh /path/to/projects

# Show help
./cargo-clean-recursive.sh --help

The script handles various error conditions:

• Missing Workspace Dependencies: Detects and handles missing Cargo.toml files in workspace members
• Malformed Manifests: Validates and skips Cargo.toml files missing required [package] or [workspace] sections
• Dependency Validation: Validates workspace dependencies before attempting to clean
• Alternative Cleaning Methods: Falls back to direct target directory removal when cargo clean fails
• Graceful Degradation: Continues processing other projects when individual projects fail

• Enhanced workspace dependency error detection
• Added validation for missing dependency files
• Added validation for malformed Cargo.toml files
• Improved error messages with specific file information
• Better handling of workspace member manifest loading errors
• More robust fallback cleaning strategies
