chore: bootstrap project structure (.tasks, .wiki, CLAUDE.md)

Adds canonical Karpathy LLM Wiki layout, .tasks/STATUS.md board,
and CLAUDE.md trigger set. Brings factory repo into projects-meta
indexing eligibility (sync-runner.ts:69 — needs .tasks/STATUS.md or
.wiki/index.md on default branch).

Bootstrap-manifest at .wiki/concepts/bootstrap-manifest.md records
skill versions used (project-bootstrap@1.7.0, layouts inline-fallback
from setup-wiki@1.0.0 / setup-tasks@1.0.0).

+# Wiki Schema — factory
+
+Project-specific wiki conventions. Read this before any wiki operation.
+
+This wiki follows Karpathy's LLM Wiki pattern:
+**https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f**
+
+The `using-wiki` skill enforces the workflow and file formats. This file overrides the skill where they conflict.
+
+## Page types
+
+- `entities/` — discrete things the project tracks (people, services, modules).
+- `concepts/` — recurring ideas, design decisions, gotchas.
+- `packages/` — code packages this project produces or consumes.
+- `sources/` — one summary page per ingested external doc; frontmatter carries `ingested:` and `raw_path:`.
+- `overview.md` — single project-wide overview.
+
+## Naming
+
+- `kebab-case.md`, **Latin only**. Transliterate Cyrillic in filenames; keep the original title in the H1 + frontmatter.
+
+## Domain conventions
+
+<!-- factory-specific naming idioms — fill in as the project takes shape. -->
