Add comprehensive dry-run functionality to the Rust implementation that allows users to test their configuration without making any changes to CouchDB: - Added --dry-run/-n command line flag with clap argument parsing - Extended CommandLineArgs struct with dry_run field - Updated bash completion script to include new flag - Comprehensive dry-run logic throughout sync coordinator: - Skip database creation with informative logging - Skip sync metadata retrieval and use config fallback - Skip deleted message handling in sync mode - Skip message and attachment storage with detailed simulation - Skip sync metadata updates with summary information - Enhanced summary output to clearly indicate dry-run vs normal mode - Updated all tests to include new dry_run field - Maintains all IMAP operations for realistic mail discovery testing This brings the Rust implementation to feature parity with the Go version for safe configuration testing as identified in ANALYSIS.md. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
