#21 Add Amazon Redshift connector/runtime

[Anonymous]

Originally created by: intraq-dev-ai

Connector gap

WrenAI supports Amazon Redshift. IntraQ currently maps redshift to PostgreSQL dialect in SQL helpers, but Redshift is not a first-class live connector.

Evidence

WrenAI docs list Amazon Redshift as a supported data source. IntraQ live SQL execution currently supports PostgreSQL, MySQL/MariaDB, SQL Server, Databricks, and ClickHouse.

Acceptance criteria

• Add Redshift as a first-class selectable connector.
• Support Redshift connection configuration and SSL defaults.
• Support schema discovery, query preview, SQL Editor execution, Analyzer, and Dashboard Builder.
• Add tests for Redshift-specific connection handling and SQL limit behavior.
