Fix false-positive broken-edge findings in ckb-lint graph check

Graph edge endpoints use project-root-absolute paths per Rule C
(`/wiki/entities/foo.md`), while the `known` page set is keyed on paths
relative to `wiki/`. check_graph compared them directly, so every
conformant edge was reported as pointing at a missing page. Add the
`/wiki/`-stripped form to the candidate set, matching the normalisation
the decision-record check already performs.

Bump VERSION 1.6.0 -> 1.6.1.

 - Graph gained `decided_by` (decision → person) and `affects` (decision → constrained entity) edge types.
 - Docs updated in both languages (README/README.pl feature + skill sections, MANUAL/MANUAL.pl new §2.D walkthrough and "say this" table rows, ownership table row noting the append-only convention), plus `ckb-init` (scaffold + skill list). Also fixed five stale `cbk-quiz` path references left from the upstream rename.
 - End-to-end tested on a scratch copy: a sample decision record passes lint clean and exports to OKF conformantly. That test surfaced a real bug in `export_okf.py` — a Rule B log line naming a directory (`wiki/decisions/` (directory)) was being turned into a broken intra-bundle link; `files_to_links` now only linkifies entries that name an actual `.md` file.
+- Fixed a second bug in `lint_report.py`'s `check_graph`: graph edge endpoints are project-root-absolute per Rule C (`/wiki/entities/foo.md`), but the `known` set holds paths relative to `wiki/`, so every conformant edge was reported as pointing at a missing page. The candidate set now also tries the `/wiki/`-stripped form, matching what the decision-record check already did. Root `VERSION` 1.6.0 → 1.6.1 (patch).
