Improves the rover iterate command experience by using the common display utilities and simplifying the command flow. The changes make the output cleaner, more consistent with other CLI commands, and easier to follow.

Changes

• Refactored the iterate command to use showTitle() and showProperties() for consistent output formatting
• Replaced verbose chat messages with clean task property displays
• Integrated ProcessManager for step-by-step progress feedback during iteration creation
• Simplified iteration context retrieval using the TaskDescriptionManager.getLastIteration() method
• Moved task loading and workspace validation earlier in the command flow for better error handling
• Removed getLatestIterationContext() helper in favor of using task manager methods directly
• Updated success tips to include iteration number in logs and inspect commands

Notes

Closes #310

The --interactive option has been commented out in preparation for future implementation.
