fix(project-bootstrap): align wiki init with Karpathy canon

Bootstrap was creating .wiki/SUMMARY.md + WORKFLOW.md + source/ — none of
which match Karpathy's LLM Wiki pattern or what wiki-maintainer reads first.
The skill had to bend around an invented layout (no schema file, wrong
catalog name, missing log/overview/entities/concepts/packages).

Rewrote Step 3 to create the canonical layout verbatim:
  .wiki/CLAUDE.md          schema (project-specific conventions)
  .wiki/index.md           catalog
  .wiki/log.md             append-only op log
  .wiki/overview.md        project overview
  .wiki/raw/README.md      immutability note
  .wiki/{entities,concepts,packages,sources}/.gitkeep

Pinned the gist URL inside the schema:
  https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f

Bumped dist/project-bootstrap.skill, recorded the why in
.wiki/source/wiki-realignment.md, and queued migration of *this* repo's own
.wiki/ (still on the old layout) as a backlog task — to be done deliberately.

+# Wiki realignment to Karpathy canon
+
+_2026-04-28._
+
+## What was wrong
+
+`project-bootstrap` Step 3 was creating `.wiki/SUMMARY.md`, `WORKFLOW.md`,
+and a `source/` folder. **None of these match** Karpathy's LLM Wiki pattern
+or what the `wiki-maintainer` skill reads:
+
+| Bootstrap created | Canon expects |
+|---|---|
+| `SUMMARY.md` | `index.md` |
+| `WORKFLOW.md` (duplicates skill) | (no such file — workflow lives in `wiki-maintainer`) |
+| `source/` (singular) | `sources/` (plural) |
+| (missing) | `.wiki/CLAUDE.md` schema |
+| (missing) | `log.md` (append-only op log) |
+| (missing) | `entities/`, `concepts/`, `packages/`, `overview.md` |
+| (missing) | `raw/README.md` |
+
+When `wiki-maintainer` triggered, it had to bend around an invented layout:
+the schema file it expects to read first wasn't there at all, and the
+catalog had the wrong name.
+
+## Fix
+
+Rewrote `project-bootstrap` Step 3 to create the canonical layout verbatim:
+
+```
+.wiki/
+  CLAUDE.md          schema (project-specific conventions)
+  index.md           catalog of all pages
+  log.md             append-only op log: ## [YYYY-MM-DD] op | desc
+  overview.md        single human-readable project overview
+  raw/README.md      raw/ is immutable; this documents that
+  entities/ concepts/ packages/ sources/   (with .gitkeep)
+```
+
+Each file has its initial content baked into the SKILL.md so bootstrap can
+write them without external assets.
+
+The Karpathy gist is pinned at the top of `.wiki/CLAUDE.md`:
+**https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f**
+
+## What about this repo's `.wiki/`?
+
+This repo was itself bootstrapped with the old buggy layout. Its `.wiki/`
+still uses `SUMMARY.md` + `source/`. Migrating to canon is a directory
+rename + file moves; queued as a backlog task to do consciously rather than
+silently bundling it here.
