Added Amazon MSK IAM authentication, along with connection and trigger updates:

• Added the IAM Access Key and Secret and IAM Role ARN connections for Amazon MSK clusters that use IAM access control
• Added a required AWS Region dropdown to the IAM Access Key and Secret and IAM Role ARN connections for selecting the region of the Amazon MSK cluster
• Updated the Schema Registry API Key field on the Basic Authentication connection to a masked password field
• Updated the Kafka Consumer trigger to group From Beginning, Auto Commit, and Deserialize Keys as Avro into a Consumer Options structured object, and to show Session Timeout (ms) and Heartbeat Interval (ms) as top-level inputs again in place of the Session Timing group
• Updated the Kafka Consumer trigger to fail the run when the consumer cannot start, such as when it cannot join its consumer group, and to reject a Max Messages value below 1
• Updated the Publish Messages action to close its broker connection when sending messages fails

Enhanced component capabilities:

• Updated the Select Topic data source to read the cluster address from the Brokers input so topic dropdowns resolve (breaking: the data source's Broker input was removed, so previously configured values must be re-entered)
• Grouped the Session Timeout and Heartbeat Interval inputs on the Kafka Consumer trigger into a Session Timing structured object
• Added output schemas across all actions for improved field mapping during configuration
• Added inline action calling support across all actions for improved example output during configuration

Added Confluent Schema Registry Avro deserialization support for the Kafka Consumer trigger:

• Automatically decoded consumed Avro-encoded message values to JSON objects
• Added optional Deserialize Keys as Avro input for key deserialization

Updated spectral version

Added global debug support across all actions for improved troubleshooting

Added comprehensive Kafka consumer/subscriber functionality and enhanced connection security.
