Adds focused coverage for task-domain view mapper DTO contracts, including summary cloning, task run/detail mapping, flow view/detail mapping, and implicit summary computation.
Test-only PR. Verified with git diff --check and PNPM_CONFIG_VERIFY_DEPS_BEFORE_RUN=false pnpm test src/tasks/task-domain-views.test.ts on the current-main merge result.
Thanks @leno23.
