[WIP] Create input layer in presentation structure

[Copilot]

Proposal 1: Create Input Layer

This PR implements the first step of the Presentation Layer Reorganization refactoring by establishing an explicit Input Layer in the presentation structure.

Progress:

• Phase 1: Create Directory Structure
  • Create src/presentation/input/ directory
  • Create src/presentation/input/mod.rs with module documentation
  • Verify directory structure
• Phase 2: Move CLI Module
  • Move src/presentation/cli/ to src/presentation/input/cli/
  • Verify files moved correctly
  • Old src/presentation/cli/ directory removed (by move operation)
• Phase 3: Update Imports
  • Update src/presentation/mod.rs
  • Update all files that reference presentation::cli
    • src/presentation/commands/mod.rs
    • src/presentation/commands/create/mod.rs
    • src/presentation/commands/create/handler.rs

    • src/presentation/commands/create/tests/integration.rs
    • src/presentation/input/cli/args.rs (internal references)
    • src/presentation/input/cli/mod.rs (internal references)
• Phase 4: Documentation Updates
  • Update refactor plan with completion status
  • Add spell check words to project-words.txt
• Phase 5: Testing & Verification
  • Build succeeds without warnings
  • All tests pass
  • CLI commands work correctly

<issue_title>Proposal 1: Create Input Layer</issue_title>
<issue_description>## Overview

Establish an explicit Input Layer in the presentation structure by creating src/presentation/input/ and moving the CLI module there. This is the first step in transforming the presentation layer into a four-layer architecture (Input → Dispatch → Controllers → Views).

Parent Epic: #154 - Presentation Layer Reorganization
Related: Refactor Plan | Design Proposal

Impact: 🟢🟢 Medium - Clear separation of user input parsing from command execution
Effort: 🔵🔵 Medium - Straightforward move with import updates
Estimated Time: 2-3 hours

Goals

• Create src/presentation/input/ directory with proper module structure
• Move src/presentation/cli/ to src/presentation/input/cli/
• Update all imports from presentation::cli to presentation::input::cli
• Add module documentation explaining the input layer's purpose
• Document this as first step in refactor plan
• Ensure old structure (commands/, user_output/) remains functional

🏗️ Architecture Requirements

DDD Layer: Presentation
Module Path: src/presentation/input/
Pattern: Input Layer (Layer 1 of 4-layer presentation architecture)

Target Structure

After this proposal:

src/presentation/
├── input/                    # ← NEW: Layer 1 - Input parsing
│   ├── mod.rs                #    Re-exports cli module
│   └── cli/                  #    ← MOVED from presentation/cli/
│       ├── mod.rs            #    Main CLI structure
│       └── global.rs         #    Global arguments
├── commands/                 # ← UNCHANGED (for now)
├── user_output/              # ← UNCHANGED (for now)
├── progress.rs               # ← UNCHANGED (for now)
└── errors.rs                 # ← UNCHANGED

Implementation Plan

Phase 1: Create Directory Structure (30 minutes)

• Create src/presentation/input/ directory
• Create src/presentation/input/mod.rs with module documentation
• Verify directory structure

Phase 2: Move CLI Module (30 minutes)

• Move src/presentation/cli/ to src/presentation/input/cli/
• Verify files moved correctly
• Remove old src/presentation/cli/ directory

Phase 3: Update Imports (60 minutes)

• Update src/presentation/mod.rs: pub mod input;
• Update src/main.rs: use torrust_tracker_deployer_lib::presentation::input::cli::Cli;
• Search for all usages: rg "use.*presentation::cli" --type rust
• Update each file found with new path presentation::input::cli

Phase 4: Documentation Updates (30 minutes)

• Add completion note to refactor plan
• Update README.md if it references presentation structure
• Verify all documentation links still work

Phase 5: Testing & Verification (30 minutes)

• Run pre-commit checks: ./scripts/pre-commit.sh
• Verify all commands work: cargo run -- --help, etc.
• Verify no compilation warnings

Acceptance Criteria

@copilot The PR has been rebased onto the latest main branch and is ready for you to continue working.

Context: The previous timeout issue that was blocking progress (caused by pre-commit checks taking longer than the command execution timeout) has been resolved in #121. The E2E tests are now skipped in the Copilot agent environment using the TORRUST_TD_SKIP_SLOW_TESTS environment variable, which reduces pre-commit execution time to under 5 minutes.

You can now continue with the implementation of this PR. All phases are marked as complete in the description, but please verify the current state and proceed with any remaining work or testing.

[josecelano]

@copilot, before committing, make sure the environment variable TORRUST_TD_SKIP_SLOW_TESTS is set to true to skip slow tests. Otherwise, pre-commit checks take longer than the bash command execution, and we reach the whole session timeout (30") trying to commit in an infinite loop.

[josecelano]

I will do it with a local agent.
