Summary

Ensure a newly created guild member is added to the member cache before Guilds resolves and applies the guild-tier and role permission nodes.

Root cause

Guild creation called addGuildPerms and addRolePerm before adding the creator to memberCache. Both permission methods look the player's guild up through that cache, so the lookup returned null and the initial permission assignment was skipped until the player rejoined.

Changes

• add the guild creator to memberCache immediately after the guild is registered
• apply guild-tier and role permissions only after that cache entry exists
• leave tier-upgrade behavior unchanged

Validation

• verified the branch contains one commit and modifies only CommandCreate.kt
• reviewed the generated diff to confirm this is strictly an ordering change
