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.
