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.

Add comprehensive dry-run functionality that allows users to test their
configuration without making any changes to CouchDB. The feature includes:
- New --dry-run/-n command line flag with help and completion support
- Skips all CouchDB write operations while preserving IMAP operations
- Provides detailed logging of what would be done in normal mode
- Shows sample message data and metadata updates that would occur
- Maintains all existing functionality when dry-run is disabled
This addresses the critical usability need identified in ANALYSIS.md for
safe configuration testing before making database changes.
