Summary

• Distinguish whole-script clips from script-step clips and explain where each can be pasted.
• Document the workflow for updating steps inside an existing script, including converting an already-copied whole script.
• Warn against deleting and renaming scripts as a replacement strategy because script identity and references are not preserved by name alone.

Closes #273.

Validation

• git diff --check passed.
• Verified menu labels and clipboard behavior against the current implementation.
• Documentation-only change; application tests not run.
