Adds docs/agents/{issue-tracker,triage-labels,domain}.md so the engineering
skills know where issues live (Gitea via tea, not gh), which triage labels to
apply, and that domain docs are single-context.
Every CLAUDE.md was a stale subset of the AGENTS.md beside it, so each is now
a symlink and AGENTS.md is the single source of truth.
