📝 docs(readme): add an "Open in StackBlitz" badge to the README badge rows

[vtempest]

Adds an Open in StackBlitz badge to every badge row in this repo.

StackBlitz installs from the manifest at the path it is handed, so each badge points at a directory that boots on its own rather than at the repo root:

Badge row	Opens
README.md	examples/basic-request — the self-contained example the docs already open with <StackBlitzExample>
grab-help-docs/content/docs/index.mdx (the same row, on the docs home)	examples/basic-request
packages/quantum-sphere-loading-animation/README.md	that package

The badge sits next to the existing "Open in GitHub Codespaces" badge in each row, using StackBlitz's own open_in_stackblitz.svg.

No code, build or docs-pipeline changes — Markdown/MDX only.

The test check is red on this PR's head, and it is not this PR's failure — this branch changes three Markdown/MDX files and nothing else.

The same check is red on master. The last six runs of tests.yml on master all failed, starting with the merge of #45; the last green one was #44's merge (run 159). This branch is based on #50's merge, which is already inside that red stretch.

Root cause. packages/grab-url-cli/src/transfer/ytdlp-transfer.ts is missing six symbols that both packages/grab-url-cli/src/index.ts (lines 123-131) and test/page-archive.test.ts (line 32) import from it: findYtDlp, probeYtDlp, runYtDlpDownload, ytDlpInstallHint, parseYtDlpSize, parseYtDlpEta. The module exports buildYtDlpArgs, parseYtDlpProgress and describeYtDlpExit, and the test's vi.mock(..., importOriginal) spread cannot produce the rest — hence [vitest] No "parseYtDlpSize" export is defined on the ... mock on eleven cases. The remaining assertion failures in the same file (buildYtDlpArgs output template, parseYtDlpProgress returning null, the describeYtDlpExit message) are the same drift: the tests describe a version of that module that did not land.

No fix exists to port — the only other open PR, #53, is a publish-provenance change. Fixing this means writing the missing yt-dlp transfer functions, which is well outside a badge-row PR, so I am not widening this one to carry it. Skipping the re-run too: six consecutive red runs on master and a symbol that is absent from the source are not a flake.

master needs that fix on its own; this PR is mergeable as soon as it lands, and nothing here blocks it.

Second red check on this head, also not this PR's: Vercel (grab-url project) errored.

The bot's own payload still reports "rootDirectory":"docs", which is the failure this repo already has written down in .claude/architecture/documentation.md — "The Vercel deploy is broken, and docs/ is why". The project's Root Directory has pointed at docs since the docs app was renamed docs/ → grab-help-docs/; turbo resolves no package from there, never writes a .next, and the deploy fails looking for docs/.next/routes-manifest.json. Every deployment of that project is failing, production included.

Quoting that note: "This is a dashboard setting, not a diff — no commit can fix it", and "until that setting changes, a red Vercel check on a PR here says nothing about that PR." The fix is in the Vercel dashboard: Root Directory → grab-help-docs, clear the npm install --prefix=.. Install Command override, leave Build Command unset.

So both red checks on this branch are pre-existing: test (missing ytdlp-transfer exports on master, above) and Vercel (this dashboard setting). Neither is fixable from a Markdown-only PR.
