* feat(scripts): add static website generator from markdown sources (#85)

Generate an elegant, mobile-friendly static site from the existing
tutorial markdown files. The markdown remains the single source of
truth — `scripts/build_website.py` reads from the same `.md` files the
EPUB builder uses, rewrites cross-references to site URLs, and rewrites
references to non-markdown repo files (`.json`, `.sh`, `.py`) to
GitHub blob URLs so users can jump to the source on github.com.

Highlights:
- Reuses the chapter ordering convention from `build_epub.py`
- Anchor algorithm mirrors `check_cross_references.heading_to_anchor`
  for parity with the validator
- Mermaid renders client-side via `mermaid.js` (no pre-render step)
- Tailwind CSS via CDN; light/dark theme toggle; sidebar nav; in-page
  TOC; prev/next page navigation; mobile responsive
- 27 unit + smoke tests covering anchors, link rewriting (including
  `<source srcset>` inside `<picture>`), Mermaid handling, and a full
  end-to-end build
- GitHub Pages deploy workflow at `.github/workflows/pages.yml`

Closes #85

* fix(website): use relative URLs in sidebar nav and avoid INDEX.html collision

Two bugs found by local browser dogfooding:

1. **Sidebar nav broke from deep pages.** `build_navigation` emitted raw
   `output_url` values (site-root-relative) which made every sidebar link
   404 from any page below the root. Moved the call inside the per-page
   render loop so each page gets nav links computed relative to its own
   URL — `01-slash-commands/index.html` from the root, `../01-slash-commands/...`
   from a depth-1 page, `../../01-slash-commands/...` from depth-2.

2. **`INDEX.md` overwrote `index.html`.** On case-insensitive filesystems
   (macOS/Windows), `INDEX.html` and `index.html` are the same file, so
   `INDEX.md` clobbered the rendered `README.md`. Added `_disambiguate_url`
   that detects case-insensitive collisions and suffixes the colliding
   page with its source stem (`INDEX-index.html`).

Added 2 tests; full suite stays at 83 passed.

* fix(scripts): skip URLs with port in localhost/127.0.0.1 skip list

`check_links.is_skipped()` did an exact-match comparison against the
host, so `http://localhost:8080` (used in scripts/README.md as a preview
example) was not skipped and CI's link check tried to fetch it, which
fails on the GitHub runner. Strip the port before comparing.

* chore(scripts): drop vestigial mypy ignore_errors for build_website

The override silenced all mypy errors for build_website, making the
"mypy: clean" claim technically vacuous. Removing it shows mypy is
actually clean — 0 issues on build_website after type annotations
were added during PR review.

* feat(website): self-host Tailwind, Mermaid, and Inter fonts

Drop all third-party CDN dependencies from rendered pages. The site
previously loaded Tailwind from cdn.tailwindcss.com (Play CDN — JIT
compile in browser, marked not-for-production), Mermaid from
cdn.jsdelivr.net, and Inter/JetBrains Mono from fonts.googleapis.com.

Replace with a vendored toolchain:

- scripts/vendor_assets.py downloads the Tailwind standalone CLI
  (Go binary, no Node toolchain), Mermaid's UMD bundle, and Google
  Fonts CSS + WOFF2 files. Cached under scripts/.vendor-cache/
  (gitignored), refetched only when missing.
- Tailwind compiles a per-build site/assets/tailwind.css with only
  the utility classes actually used by the rendered HTML.
- Mermaid and font files land in site/assets/vendor/ and load via
  relative URLs.
- Tailwind config + entry CSS live in scripts/website_templates/
  alongside the Jinja template.
- build_website grows a skip_vendor flag so the smoke test runs
  offline.
- pre-commit mypy hook gets types-Markdown so it can resolve the
  same imports as the project venv.

Verification: 86/86 pytest pass, ruff/mypy/bandit clean, full
build produces a working site with zero external requests (verified
in a headless browser — no console errors, no failed network calls,
Mermaid diagrams render).
