Pre-Deployment 'Dry Run' Framework for SQL Migrations

Act as a Database CI/CD Pipeline Architect. Engineer a highly advanced 'Dry Run' simulation stage deeply embedded within the [CI_CD_TOOL] pipeline that executes a proposed database migration entirely within an isolated SQL transaction that is mathematically guaranteed to `ROLLBACK` upon completion. The simulation framework must actively intercept and capture all generated database warnings, calculate precise execution duration times, and aggressively monitor total lock acquisition counts generated by the [DATABASE_ENGINE]. You must script the logic to compile this raw telemetry data and output it into a highly readable, structured [REPORT_FORMAT] (e.g., Markdown table with Red/Green highlights). This report must be automatically injected as a sticky comment directly on the developer's Pull Request, explicitly visualizing the exact performance impact the migration will have on the production cluster without making a single permanent data mutation.
