* Add dry-run support across destructive commands

Implement dry-run for uninstall, purge, installer, touchid, completion, and remove flows.\nGuard side effects in uninstall path (launchctl, defaults writes, kill/brew actions), update help/README, and add coverage in CLI/Bats tests.\n\nValidation: ./scripts/check.sh and ./scripts/test.sh (452 tests, 0 failures, 8 skipped).

* test(purge): keep dev-compatible purge coverage
