Implement output formatters and interaction strategies

[Sstark97]

Phase 5: CLI Presentation

Implement output formatters and user interaction strategies.

Output Formatters (IOutputFormatter Strategy)

In Infrastructure/Cli/Output/:

SpectreOutputFormatter

• Uses Spectre.Console for rich terminal UI
• Markup for colors: [green], [red], [yellow]
• Tables for analysis reports
• Spinners for long operations
• Progress bars for cleanup
• Banner with ASCII art
• Replaces all bash log_* functions and print_banner/print_completion

PlainTextOutputFormatter

• Plain text, no ANSI codes
• For CI/CD, piping, logging
• Simple line-by-line output
• Tables as plain text with alignment

JsonOutputFormatter

• Structured JSON output
• For MCP server, scripting, automation
• All data serializable
• Example:

{
  "timestamp": "2026-02-07T...",
  "mode": "analyze",
  "totalEstimatedSize": "15.3GB",
  "targets": [...]
}

User Interaction Strategies (IUserInteraction Strategy)

In Infrastructure/Cli/Interaction/:

InteractiveConsole

• Human interactive mode
• Prompts user for confirmations
• Different prompts per ConfirmationLevel:
  • Simple: "Continue? (y/N)" - skipped with --force
  • Dangerous: Type "yes" - skipped with --force
  • Nuclear: Type "yes" - NEVER skipped, even with --force
• Uses Spectre.Console ConfirmationPrompt and TextPrompt

AutoConfirmInteraction

• For MCP server, CI/CD
• Auto-confirms everything (no prompts)
• Equivalent to --force but programmatic
• Returns true for all confirmations except Nuclear
• Nuclear still requires explicit "yes" from caller

InteractiveMenu

• Multi-select module menu using Spectre.Console MultiSelectionPrompt
• Loop for "cleanup more?" - ask_continue_cleanup
• Replaces bash show_interactive_menu and show_multiselect_menu

Tests Required

All in tests/Infrastructure/Cli/:

Output Tests:

• Output/SpectreOutputFormatterTests: Markup rendering, table formatting
• Output/PlainTextOutputFormatterTests: Plain text output
• Output/JsonOutputFormatterTests: JSON serialization, schema validation

Interaction Tests:

• Interaction/InteractiveConsoleTests: Confirmation levels, force mode
• Interaction/AutoConfirmInteractionTests: Auto-confirm behavior
• Interaction/InteractiveMenuTests: Menu display, module selection

Port tests from bash tests/unit/analyze_mode_test.sh for display formatting.

Definition of Done

• All 3 output formatters implemented
• All 2 interaction strategies implemented
• Interactive menu working with Spectre.Console
• Tests verify each formatter/strategy
• --output flag selects correct formatter
• MCP-ready with AutoConfirmInteraction + JsonOutputFormatter
