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.

 | [[Agent Docs and Edits]] | Two self-inflicted doc damage classes from parallel agent edits, with the audit checks and recovery order for each. |
 | [[Command Center Dotfiles]] | How the dotfiles repo deploys: stow-equivalent packages, full-replica rsync, the pre-overwrite audit, transport gotchas. |
+| [[Domain Docs]] | Consumer rules for GLOSSARY.md and docs/adr/, and where this vault out-ranks them on operational facts. |
+| [[Issue Tracker]] | How agent skills read and write Gitea issues here: credential-safe curl, label IDs, and wayfinding without sub-issues. |
 | [[OMP Harness]] | The omp harness as configured here: compaction chain arithmetic, per-model sampler routing, and the context-lean audits. |
+| [[Triage Labels]] | The five canonical triage roles mapped to this repo's Gitea label strings, plus the numeric-ID quirk. |
