Agent Skills: multi-user-workflow-generator

Generates multi-user workflow documentation by interviewing the user about personas, exploring the codebase for multi-user patterns, then walking through the live app with per-persona Playwright browser contexts to co-author interleaved, persona-tagged workflows. Use when the user says "generate multi-user workflows", "create multi-user workflows", or "generate concurrent user workflows". Produces persona-tagged workflow markdown that feeds into the multi-user converter and Playwright runner.
