- Replace mysql-connector-python with PyMySQL driver for better MariaDB compatibility - PyMySQL handles utf8mb4_0900_ai_ci collation properly without errors - Update Dockerfile.sql-executor to install PyMySQL and psycopg2-binary - Refactor sql-query-executor.py to use PyMySQL API (pymysql.connect, DictCursor) - Verified sql-executor service with SELECT, INSERT, UPDATE operations on Freescout DB - Add n8n workflow definitions: workflow-a-http.json and workflow-b-http.json * Workflow A: Polls unprocessed conversations, analyzes with LiteLLM, saves suggestions * Workflow B: Polls approved suggestions, executes Baramundi jobs or email replies - Update compose.yaml with sql-executor service configuration and dependencies All SQL operations now execute successfully against MariaDB 11.3.2
