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.
