## Title

    Proposed fix: [librdkafka / confluent-kafka] 'No provider for SASL mechanism GSSAPI: recompile librdkafka with libsasl2 or openssl support' — sasl.mechanisms left at default GSSAPI when enabling SASL

## Body

    Recommended action: Set sasl.mechanism (alias of sasl.mechanisms) explicitly to the provider's mechanism (e.g. PLAIN for Confluent Cloud/Event Hubs, SCRAM-SHA-512 for MSK SCRAM) with credentials; only rebuild librdkafka with libsasl2 if you really need Kerberos.
    
    Option: Set the mechanism explicitly [evidence: official_recommended_action]
    Applies when: See record scope.
    Steps:
    1. {'security.protocol':'SASL_SSL','sasl.mechanism':'PLAIN','sasl.username':KEY,'sasl.password':SECRET}
    Expected: Command proceeds without the error.
    
    Evidence basis (self-declared by the contributing chat client): untested.
