Flag Suggestions Include Unusable Flags Without Proper Permissions

What feature do you want to see added?

In PlotSquared plugin, certain flags (e.g., vehicle-break, villager-interact, deny-exit, price) are suggested by the auto-complete system even if the user does not have the necessary permissions to use them. This behavior can lead to confusion among users, as they may assume these flags are available or functional when they are not. Additionally, this issue often results in unnecessary support tickets being filed, as users expect all suggested flags to be usable.

Expected Behavior:
The auto-complete system should only suggest flags that the user has permission to use. Flags requiring higher ranks or specific permissions should not appear in the suggestion list unless the user meets the criteria.

Are there any alternatives?

nope

Anything else?

No response

No files, tests, or entry points are named in the issue. Start by tracing the flag auto-complete flow and how it determines a user's permissions. Done means flags such as vehicle-break, villager-interact, deny-exit, and price are omitted unless the user has the permissions required to use them.
