Website audit: fix factual inaccuracies, relocate Too Many Cooks, add dart_node_sql_js

[MelbourneDeveloper]

TLDR

Hard audit of the docs website: stubs out the relocated Too Many Cooks, fixes factual inaccuracies (publisher, GitHub casing, social handle, stale versions, broken links, wrong API code examples), surfaces the published dart_node_sql_js, and repairs SEO/social metadata.

What Was Added?

• dart_node_sql_js surfaced everywhere it was missing: homepage stack card (en/zh), homepage ItemList schema, docs nav (en/zh), API index (en/zh), a generated docs page, and a new Chinese README (packages/dart_node_sql_js/README_zh.md). Added to the docs-generation and API-generation pipelines.
• og-image.png (1200×630) and apple-touch-icon.png (180×180) — the social-card/JSON-LD image and apple-touch-icon were referenced everywhere but the files did not exist (404). Generated branded assets.
• nimblesite.co copyright link in the footer.

What Was Changed or Deleted?

• Too Many Cooks moved to https://tmc-mcp.dev: homepage cards (en/zh) and the MCP & vsix READMEs now point there and state it is no longer part of this repo. Removed from the homepage package ItemList (it is not a dart_node package).
• Factual corrections (sitewide): pub.dev publisher dartnode.dev → christianfindlay.com (verified); GitHub casing → MelbourneDeveloper; X/Twitter @dart_node → @cfdevelop (the real, active handle).
• Unpublished packages (dart_jsx, dart_node_vsix, both publish_to: none) no longer link to 404 pub.dev pages — they link to GitHub source. The docs-generator does this automatically for any unpublished package.
• Broken links: footer /docs/examples/ (no such page) → GitHub examples; 125 broken /api/../… dartdoc cross-links fixed by collapsing the full leading ../ run in the API link rewriter.
• Stale versions: install snippets ^0.11.0-beta → ^0.13.0-beta (latest published); wrong nadz: ^0.9.0 → ^0.0.7-beta (actual constraint).
• Code examples in package READMEs/blog corrected to the real package APIs (react text()→string / p()→pEl / Document.getElementById / button(text:); react_native image()→rnImage, flatList signature, ScreenProps; express req.params access + dart:js_interop_unsafe import + router mount; mcp full 5-field ToolConfig; better_sqlite3 Result handling; logging LogFunction transport signature).
• dart-to-js doc: -O1 is the dart2js default (was wrongly -O2), removed a reference to a nonexistent build tool, fixed the --dump-info reference.
• Removed a phantom SearchAction from the WebSite JSON-LD (no /search route exists); shortened an over-long (67-char) blog <title>.
• Upgraded eleventy-plugin-techdoc 0.1.0 → 0.2.0 and @11ty/eleventy → 3.1.6, and audited the upgraded output.

How Do The Automated Tests Prove It Works?

• npm run build completes with 0 warnings / 0 errors across all 10 packages' dartdoc + Eleventy (2424 pages), including the newly-added dart_node_sql_js API docs.
• A full internal-link crawl of the generated _site dropped broken targets from 177 → 52; every remaining target is pre-existing (see below), and a string sweep confirms 0 occurrences of the old publisher / GitHub casing / @dart_node / /docs/examples / too_many_cooks package links.
• Each code-example change was reviewed in the git diff against the actual package lib/ (and test//example/) — e.g. flatList(JSArray data, JSFunction renderItem, props:), ToolConfig 5-field record matching runtime_test.dart, LogFunction = void Function(LogMessage, LogLevel) matching log_to_console.dart.
• Playwright (1280×720 and 375×667): homepage, /docs/react/, /docs/sql-js/ (en/zh), /docs/getting-started/ load with no console errors; og-image.png/apple-touch-icon.png return 200.

Known pre-existing issues (not introduced here, out of scope): 40 links on the dart_logging API landing page (its two-library dartdoc layout isn't mapped to member pages by the generator), 10 hreflang/language-switcher links to untranslated zh blog pages, and 2 reflux dartdoc self-links.

Spec / Doc Changes

This PR is primarily docs/website. Package README.md/README_zh.md files were edited (they are the source for the generated docs pages); no library code, pubspecs, or tests were changed.
