docs: Agent-Skills-Konfiguration fuer den Gitea-Tracker hinterlegen

Die Engineering-Skills (wayfinder, triage, to-tickets, to-spec) erwarten pro
Repo eine Tracker-Beschreibung. Hier ist das Gitea, nicht GitHub oder GitLab -
der Host heisst zwar gitlab.hive-brain.de, spricht aber die Gitea-API, also
tea statt glab.

Issue-Dependencies und Sub-Issues kann tea 0.15 nicht abbilden; beides ist in
der Doku als ungeprueft bzw. mit Body-Konvention als Fallback vermerkt, damit
keine Session sich auf ungetestete Kommandos verlaesst.

+# Triage Labels
+
+The skills speak in terms of five canonical triage roles. This file maps those roles to the actual label strings used in this repo's issue tracker.
+
+| Label in mattpocock/skills | Label in our tracker | Meaning                                  |
+| -------------------------- | -------------------- | ---------------------------------------- |
+| `needs-triage`             | `needs-triage`       | Maintainer needs to evaluate this issue  |
+| `needs-info`               | `needs-info`         | Waiting on reporter for more information |
+| `ready-for-agent`          | `ready-for-agent`    | Fully specified, ready for an AFK agent  |
+| `ready-for-human`          | `ready-for-human`    | Requires human implementation            |
+| `wontfix`                  | `wontfix`            | Will not be actioned                     |
+
+When a skill mentions a role (e.g. "apply the AFK-ready triage label"), use the corresponding label string from this table.
+
+Labels are not created automatically. Create a missing one with:
+
+```bash
+tea labels create --name needs-triage --color "#ededed" --description "Maintainer needs to evaluate this issue"
+```
+
+Edit the right-hand column to match whatever vocabulary you actually use.
