refactor: [#168] integrate progress module into views layer

[josecelano]

Overview

This PR implements issue #168 by moving the orphaned src/presentation/progress.rs module into the views layer as src/presentation/views/progress/ to establish clear ownership and complete the four-layer presentation architecture.

Changes Made

✅ Module Structure

• Moved src/presentation/progress.rs to src/presentation/views/progress/mod.rs
• Updated src/presentation/views/mod.rs to include and re-export progress module
• Updated src/presentation/mod.rs to remove progress module from root
• Added progress module documentation to views layer

✅ Import Path Updates

Updated import statements in 7 files:

• 6 controller files: create/destroy subcommand handlers and error types
• 1 test file: reentrancy test

✅ Documentation Updates

• Updated all 10 documentation examples in progress module to use new import paths
• All doctests compile and pass with new import paths
• Added progress module reference in views layer documentation

Architecture Benefits

• Clear Ownership: Progress indicators are now clearly owned by the Views layer
• No Orphaned Modules: Eliminated the orphaned module at presentation root
• MVC Alignment: Progress indicators are properly categorized as view components
• Views Layer Completion: Views layer now comprehensively handles all output/formatting concerns

• No unused dependencies ✅ (cargo machete clean)
• Documentation builds ✅
• Pre-commit checks ✅

✅ API Preservation
