fix: enhance interactive mode for compatibility checks and prompts

[dermatz]

Improve Hyvä Compatibility Check UX and Code Quality

Problem

The Hyvä compatibility checker had several UX and code quality issues:

• Used MultiSelectPrompt with mutually exclusive options (e.g., "show-all" vs "incompatible-only")
• Displayed [ERROR] box when finding compatibility issues, suggesting MageForge was broken rather than modules having issues
• Magic strings throughout the code instead of constants
• Exception handling could leave terminal in broken state
• No spacing before exit, making error message appear cramped

Solution

Refactored interactive mode to use logical prompt flow and improved messaging:

1. Replace MultiSelect with Sequential Prompts

• SelectPrompt for display mode (issues | incompatible-only | show-all)
• SelectPrompt for module scope (third-party | all)
• ConfirmPrompt for detailed view (yes | no)

2. Improved Result Messaging

• Changed $io->error() to informative writeln() with icons
• Clear context: "Found X issues in Y scanned modules"
• Explains that modules need modifications, not MageForge

3. Code Quality Improvements

• Added class constants for all magic strings (DISPLAY_MODE_*, SCOPE_*)
• Changed \Exception to \Throwable for comprehensive error catching
• Moved terminal cleanup to finally block for guaranteed execution
• Added spacing before exit for better readability

Changes

• ✅ Replace MultiSelectPrompt with SelectPrompt and ConfirmPrompt
• ✅ Add constants: DISPLAY_MODE_ISSUES, DISPLAY_MODE_INCOMPATIBLE_ONLY, DISPLAY_MODE_SHOW_ALL, SCOPE_THIRD_PARTY, SCOPE_ALL
• ✅ Replace all magic string comparisons with constants
• ✅ Change error box to informative message with warning icon (⚠)
• ✅ Include module count in result message ("in 394 scanned modules")
• ✅ Move restoreTty() and resetPromptEnvironment() to finally block
• ✅ Add newLine() before exit for spacing
