v1.94.11 — fix -Action Batch headless mode (Silent + JSON)

- Fix: -Action Batch -Silent no longer cancels on the confirmation
  prompt. The confirmation is now skipped entirely in -Silent mode
  (caller already committed by invoking Batch with a config).
- Fix: -Action Batch -Silent no longer hangs on Read-Host when
  creating a local admin. Password now reads from (in priority):
  Config.LocalAdminPassword, env var named by Config.LocalAdminPasswordEnv,
  or $env:RACKSTACK_LOCAL_ADMIN_PWD. Missing -> clean failure with
  diagnostic rather than blocking.
- Fix: -Action Batch -Silent no longer hangs on the post-failure
  undo prompt. Uses Confirm-UserAction so silent-mode returns the
  safe default (skip undo) instead of blocking on Read-Host.
- Fix: -Action Batch -OutputFormat JSON now emits a machine-readable
  summary on completion. Previously Batch silently produced no JSON
  even when JSON was requested.

+## v1.94.11

+- **Fix:** `-Action Batch -Silent` no longer cancels on the confirmation prompt. Previously `Confirm-UserAction` in silent mode returned the DefaultNo answer, so every headless batch run aborted before doing anything. The confirmation is now skipped entirely in `-Silent` mode (the caller already committed by invoking Batch with a config).
+- **Fix:** `-Action Batch -Silent` no longer hangs on `Read-Host` when creating a local admin account. In silent mode the password now comes from (in priority order): `Config.LocalAdminPassword` (inline), the env var named by `Config.LocalAdminPasswordEnv`, or `$env:RACKSTACK_LOCAL_ADMIN_PWD`. If none are set, the step fails cleanly with a diagnostic instead of blocking forever.
+- **Fix:** `-Action Batch -Silent` no longer hangs on the post-failure undo prompt. The prompt now goes through `Confirm-UserAction`, which in silent mode returns the safe default (skip undo) rather than blocking on `Read-Host`.
+- **Fix:** `-Action Batch -OutputFormat JSON` now emits a machine-readable summary on completion — `{Action, Timestamp, Hostname, ConfigType, DryRun, TotalSteps, ChangesApplied, Skipped, Errors, RebootNeeded, Success}`. Previously the Batch action silently produced no JSON even when JSON was requested.
+- 65 modules, 4535 tests, 167 CLI actions, 615 functions

 ## v1.94.10
 
 - **Fix:** Batch mode now returns a meaningful exit code — `Start-BatchMode` returns the failed-step count and both CLI callers (`-Action Batch` and the auto-run from `batch_config.json`) set the process exit code accordingly. Previously both paths unconditionally exited `0`, so CI/CD orchestration couldn't detect when batch steps failed.
