docs(agent): scaffold the agent-skills config as three vault pages

Point the mattpocock-lineage skills (triage, to-tickets, to-spec,
wayfinder) at repo facts instead of a parallel docs/ tree: Gitea is the
issue tracker (credential-safe curl shape, token-only writes), the five
canonical triage roles keep their default label strings (created on the
tracker today), and GLOSSARY.md/docs/adr/ stay lazy with this vault
owning operational facts. AGENTS.md gains the ## Agent skills pointer
block; indices regenerated.

+### Issue tracker
+
+Issues live in Gitea (`dank/serverAppConfigs` on Dankclaw), via its REST API with the stored credential. See `serverAppConfigs-docs/Agent/Issue Tracker.md`.
+
+### Triage labels
+
+The five canonical roles keep their default strings (`needs-triage`, `needs-info`, `ready-for-agent`, `ready-for-human`, `wontfix`). See `serverAppConfigs-docs/Agent/Triage Labels.md`.

+### Domain docs
+
+Single-context: root `GLOSSARY.md` + `docs/adr/`, created lazily; this vault stays the owner of operational facts. See `serverAppConfigs-docs/Agent/Domain Docs.md`.
