forge-link

When you open a GitHub issue, link it to the spec node(s) it serves by adding a line to the issue body: Spec: <node-id> (comma-separate several). The id is the node's leaf name — the folder under .spec/…/<id>/spec.md, e.g. sessions, never the slash-path. An unrecognized id silently links nothing, so use a real node id (spex board lists them). A pull request needs no marker: opening it from your node/<id> branch links it for free.
