9.0.1

Fixed

• Invoke-ModuleInstall now imports the target module with -Global. Because
  the function is itself a module export, a plain Import-Module placed the
  installed module's commands in this module's session state rather than the
  caller's, so callers silently relied on command auto-loading. When two
  installed modules export the same command (e.g. a renamed/split module
  leaves an old copy behind), auto-load resolved to the alphabetically-first
  one - which could be the stale version. -Global makes the explicit import
  authoritative in the caller's scope, so resolution is deterministic.
