review: audit Discord suggestions and bugs — close fixed, open issues for remaining

[NicoRuedaA]

Summary

We should review the full list of suggestions and bugs collected in Discord. For each item:

• If it is already fixed → close it on Discord
• If it still needs work → open a proper GitHub issue here

Checklist

• Review all Discord suggestions/bugs backlog
• Close items that have been resolved in recent PRs
• Open GitHub issues for items that still need attention
• Tag each new issue with appropriate labels
