v7.0.2

• Enhancement: Replace LocalStack with ElasticMQ for SQS integration tests (mensfeld)

  • ElasticMQ is free, open-source, and requires no auth token (LocalStack 2026.x requires paid account)
  • Uses softwaremill/elasticmq-native image (~30MB vs ~1GB+, starts in milliseconds)
  • Rename setup_localstack to setup_sqs and bin/clean_localstack to bin/clean_sqs

• Fix: Allow custom polling strategy to be configured per-group via add_group (mensfeld)

  • add_group now accepts polling_strategy: keyword argument
  • polling_strategy() reads from the groups hash populated by add_group, with fallback to raw options
  • EnvironmentLoader passes polling_strategy through when parsing YAML group config
