In `@crates/nh-darwin/src/rollback.rs`:
- Line 103: Update the rollback flow around ensure_current_generation and select
to acquire one inter-process profile lock before the generation check and retain
it through selection and any recovery path, preventing concurrent profile
operations from changing the profile between validation and mutation.

Adds
nh darwin rollbackto activate a retained nix-darwin generation without rebuilding.By default, selects the nearest retained generation older than the currently selected system profile. Supports selecting a specific generation with
--to, previewing with--dry, confirmation with--ask, package diffs, and activation logs.Validates activation executables before changing the profile and checks for profile changes before proceeding. If activation fails, attempts to restore the original profile; this cannot undo partial activation effects.
