What's new?

• Added Fargate launch type support for PgBouncer, with auto-derived CPU / memory and pool sizing based on max server connections.
• Added support for Gen 8 Graviton4 RDS instance types (db.m8g, db.r8g).
• Simplified PgBouncer CloudFormation parameters — seven resource and pool-size parameters have been consolidated under a single PgBouncerCpu with auto-derivation.
• PgBouncerMaxDbConnections has been renamed to PgBouncerMaxServerConnections.

Bug fixes

• Retain the PgBouncer CloudWatch log group when PgBouncer is disabled, so existing logs aren't lost on stack update.
