Egutierrez c468b24d2b feat(0130): kanban_cpp v2 — backend Go + 5 registry parser fns + epic/sub-issues

Registry (issue 0130a):
- 5 fns infra: parse_issue_md, write_issue_md, scan_issues_dir,
  scan_flows_dir, watch_dir_fsnotify
- 3 tipos: Issue, Flow, FsEvent
- Tests round-trip + scan reales + watcher fsnotify (all PASS)
- Capability group 'kanban' nuevo (docs/capabilities/kanban.md)

Apps:
- apps/kanban_cpp/ (sub-repo) — frontend ImGui: board drag-drop,
  flows, filters, detail con CSV editors
- apps/kanban_cpp/backend/ — Go service port 8487: REST + SSE +
  fsnotify watcher, parser bidireccional MD<->SQLite cache

Issues:
- dev/issues/0130-kanban-cpp-v2.md (epic)
- 0130a parser, 0130b backend, 0130c frontend

CMakeLists.txt: add_subdirectory apps/kanban_cpp (registrado por
init_cpp_app scaffolder).

End-to-end verde: backend devuelve 189 issues + 9 flows; PATCH a
/api/issues/{id} reescribe .md (solo frontmatter, body intacto);
frontend --self-test exit 0; tests Go infra 5/5 PASS.

0130b — Backend Go kanban_cpp v2

Status: pendiente

Por que

Servicio HTTP local que sirve los issues + flows del proyecto al frontend C++. Es un wrapper fino sobre las funciones del registry de 0130a + SQLite cache + watcher.

DoD

curl http://localhost:8487/api/health devuelve 200 + counts.
curl http://localhost:8487/api/issues | jq 'length' >= 90.
curl -X PATCH /api/issues/0130 -d '{"status":"in-progress"}' reescribe dev/issues/0130-*.md (status updated, body intacto).
Despues del PATCH, suscriptor SSE recibe evento {type:"updated", id:"0130"}.
Tras mv dev/issues/0130-*.md dev/issues/completed/, watcher actualiza fila (completed=1).
go test ./... verde.

Anti-scope

No expone proposals ni capabilities (eso es MCP registry).
No autentica (local-only por ahora).
No persiste estado UI (eso lo hace el frontend).
