CRITICAL FIXES:
- Actually writes DB credentials to .env (was missing entirely!)
- Runs 'php artisan migrate --seed --force' on fresh install
- Configures pg_hba.conf for PostgreSQL password auth over TCP
- Uses chmod 775 (not 755) on storage directories
- Generates APP_KEY via 'php artisan key:generate'
- Creates storage subdirectories before setting permissions
- Sets PHP-FPM pool user to match web server user
NEW FEATURES:
- Full CLI flag support (--panel, --wings, --domain, --database, etc.)
- Environment variable overrides for all settings
- Non-interactive mode (--yes / -y) for fully automated installs
- Step progress indicator [X/Y] throughout install
- Database credentials displayed in visible green box
- APP_KEY shown in red warning box
- Input validation for FQDN
- Interactive DB credential customization
- HTTP connectivity health check
- Artisan CLI health check
- Smart defaults (auto-detect DB port, auto-generate passwords)
UI IMPROVEMENTS:
- Menus start at [1] instead of [0]
- Credential boxes use visible colored borders
- help text with usage examples
- Cleaner step/section separators
