feat(setup-wiki, using-wiki): add contradictions/ and open-questions/ as canonical page types

Extends Karpathy LLM Wiki canon with two new artifact types alongside
existing entities/concepts/packages/sources. Inspired by community
discussion that highlighted explicit tracking of surfaced tensions and
unanswered questions as missing aggregation points in the canonical
layout — they currently get scattered into concepts/ or lost in log.md.

Scope is schema-level only — no new ingest behaviour prescribed. Policy
on when to escalate an inline `> **Противоречие:**` flag into a
contradictions/<slug>.md page (and the analogous flow for
open-questions) stays the user's call.

setup-wiki [v1.0.0 → v1.1.0, MINOR — additive page types]:
- Discovery (Phase 1) now requires 6 content dirs for `noop` mode
- Phase 2 plan blocks list new dirs in greenfield + migrate
- CLAUDE.md schema template gains two page-type entries with status
  enums (contradictions: open|resolved|accepted-divergence;
  open-questions: open|answered|obsolete)
- index.md template gains two empty sections
- Phase 4a .gitkeep list, Phase 4b mkdir + touch, Phase 5 verify count
  (four → six dirs), Phase 6 report count all updated
- README.md layout tree + content-dirs sentence

using-wiki [v1.0.0 → v1.1.0, MINOR — additive type values]:
- Prerequisites: four → six content directories
- Page frontmatter type enum: + contradiction | open-question
- Per-type frontmatter extensions documented (status + affects/touches)
- File naming patterns: + contradictions/<slug>.md, open-questions/<slug>.md
- index.md sections-by-type list updated
- README.md mirrors SKILL.md changes

dist/: setup-wiki.skill + using-wiki.skill rebuilt.

project-bootstrap inline reference block intentionally untouched — it's
labelled "Reference (for context only — setup-wiki is the source of
truth)" and drift-tolerant by design.

 description: Policy skill for working with an existing `.wiki/` (Karpathy LLM Wiki pattern). Use when the user asks to ingest a document, answer from the wiki, lint/health-check it, or says "use project wiki", "обнови вики", "проверь вики", "запроси вики", "заингесть", "query the wiki". Also use when modifying any file under `.wiki/` — the workflow and formats below are mandatory, and project-specific conventions live in `.wiki/CLAUDE.md`. If `.wiki/` is missing or non-canonical, delegate to `setup-wiki` first (it has its own confirmation gate). Renamed from `wiki-maintainer` at v1.0.0.

 ## Prerequisites
 
-This skill assumes the project has a canonical `.wiki/` layout: `CLAUDE.md` (schema), `index.md` (catalog), `log.md` (op log), `overview.md`, `raw/README.md`, and the four content directories `entities/`, `concepts/`, `packages/`, `sources/`.
