Use PowerShell Safely v0.3.0

First independent release of Use PowerShell Safely, a Codex Skill for
diagnosing and safely executing boundary-sensitive Windows shell workflows
across PowerShell, native executables, and WSL.

Highlights

• Publishes the independently versioned
  junwei529/use-powershell-safely repository.
• Preserves the installable five-file package byte for byte from the recorded
  migration source.
• Includes deterministic SOURCE qualification for pre-error selection,
  native/process, text/encoding, Windows/WSL, permission, destructive, and stop
  boundaries.
• Includes an explicit-destination lifecycle tool with dry-run defaults and
  disposable install, update, rollback, drift-refusal, foreign-copy-refusal,
  and uninstall checks.

Evidence boundaries

• Local release readiness is verified for the accepted immutable candidate,
  including bounded SOURCE-forward behavior for three frozen scenarios.
• Publication does not by itself prove selection/load attribution,
  installed-copy behavior, persistent lifecycle effects, a stable installed
  copy, live WSL behavior, or broad product efficacy.
