Major Features & Enhancements

• Microsoft Copilot Studio (MCS) Connector: Full MCS connector support with OAuth OBO token exchange, new connector_user role type, and copilot_studio channel enum value (#295)
• Enhanced Multi-Tenant Authentication: Dynamic MSAL client resolution with robust authority and tenant handling for multi-tenant scenarios. Updated MSAL version (#301, #307)
