"Zero runtime dependencies" is false: mermaid-export ships puppeteer #4

Current behaviour

The repo headline says zero runtime dependencies, but mermaid-export ships puppeteer.

README.md:3: "Zero-dependency, ultra-lightweight JavaScript utility libraries". README.md:8: "A collection of tiny, focused utility packages with zero runtime dependencies."

packages/mermaid-export/package.json:46-47 declares:

"dependencies": {
    "puppeteer": "^23.0.0"

mermaid-export 1.0.0 is live on npm, so an installer pulls puppeteer (and a Chromium download) despite the headline. The package is also not listed in the README package table.

Confirm:

sed -n '1,10p' README.md
node -e "console.log(require('./packages/mermaid-export/package.json').dependencies)"
npm view mermaid-export version

Why it matters

Puppeteer is a large dependency that downloads Chromium. Someone reading "zero runtime dependencies" and installing mermaid-export gets the opposite of what was promised.

Fix shape

Scope the claim (for example "zero runtime dependencies, except mermaid-export, which drives Chrome via puppeteer") and add mermaid-export to the package table with that caveat, or move it out of this monorepo.

How you know it worked

The README no longer contradicts node -e "console.log(require('./packages/mermaid-export/package.json').dependencies)".
