Inertia v3 Upgrade Prompt and JSON Log Support in Laravel Boost v2.3.0

Laravel Boost v2.3.0 ships with a guided Inertia v2-to-v3 upgrade prompt that auto-detects the frontend adapter (React, Vue, or Svelte) and provides framework-specific migration steps. Log reading tools now support JSON-formatted entries from Monolog's JsonFormatter, LogstashFormatter, and LogglyFormatter. A PHP 8.4 bug where warnings corrupted MCP tool responses by prepending non-JSON text to stdout has been fixed. Six thin Artisan wrapper MCP tools have been removed as a breaking change, with agents now directed to use equivalent CLI commands directly.
