New internal API validates and applies add/remove edits to permission rules

What

A new internal function handles adding or removing permission rules in settings files. It checks for a number of conditions before applying a change:

  • whether enterprise-managed settings restrict edits to only managed permission rules
  • whether the rule being added is a duplicate
  • whether a tool-wide * rule should trigger a warning
  • whether writing the settings file itself failed, with a specific error message for each case
Why

This gives permission-rule editing consistent validation and clearer error messages, including proper handling of enterprise-managed settings that restrict what can be changed.
