Release v2.8.0

Changed

• laravel/mcp ^0.9 support — Widens the dependency constraint to ^0.6 || ^0.7 || ^0.8 || ^0.9. The 0.9 breaking changes are client-side only (the Laravel\Mcp\Client\Contracts\Transport contract gained setProtocolVersion(), and the MCP client now only negotiates 2025-11-25/2025-06-18); this addon ships a server and does not implement either, so no code changes were needed. Server-side gains come for free: stricter JSON-RPC params/arguments validation (-32602 on non-object payloads), a CursorPaginator fix for negative cursor offsets, and hardened OAuth dynamic client registration
