Draft versioning - full history for every response

Draft versioning brings full revision history to every piece of correspondence in Pulse. Every edit, whether made by a staff member or generated by AI, creates a new version that is preserved in the draft timeline. You can compare any two versions side by side, see exactly what changed, and restore a previous version with one click.

This is especially valuable in offices where multiple staff members contribute to a response, or where a draft goes through several rounds of approval. The full history provides accountability, prevents accidental overwrites, and makes it easy to understand how a response evolved from initial draft to final version.
