Parallel Agents for Multi-File Refactors

I need to perform a cross-cutting refactor: [describe change]. Act as a coordinator agent and break this into parallel workstreams. For each workstream: (1) identify all affected files using Grep/Glob, (2) make changes, (3) validate with a local build or test. Workstreams should be: A) Database/SQL changes with migration scripts, B) Backend template/ColdFusion changes, C) Frontend JS/CSS/HTML changes, D) Test updates, E) Documentation and changelog updates. After all workstreams complete, run the full build and test suite. Flag any cross-workstream conflicts. Generate a deployment checklist including SQL scripts to run, web server config changes, and Cloudflare cache purges.
