/**
 * Project setup routes: the client-owned part of a project's config file
 * (worktree setup commands, project actions, draft starters).
 *
 * These replace the shared UI's direct `/api/fs/*` access to
 * `~/.config/openchamber/projects/<projectId>.json`. The client no longer
 * resolves the home directory or composes the path, and every write goes
 * through the same lock the scheduled-task writers hold.
 *
 * `/api/projects` is on the JSON-body allowlist in `core-routes.js`, so
 * `req.body` is parsed here without a per-route parser.
