Setup

Configure where plan suites live and whether the plans directory is gitignored. Writes `.claude/plans-config.json` with `plansDir` (default `.claude/plans`) and `gitignore` (default `true`) keys. The planning skills (`/blueprint`, `/build`, `/qa`) read this config to resolve the plans directory, falling back to `.claude/plans` when the config is absent. Use when the user invokes `/setup`, asks to "configure the plans directory", "change where plans live", "set up the plans skill config", or wants to opt in/out of gitignoring the plans directory.
