docs: add docusaurus-plugin-copy-page-button

[portdeveloper]

What this adds

A "Copy page" button in the docs sidebar that exports the current Ionic docs page as clean markdown, with one-click "Open in ChatGPT", "Open in Claude", and "Open in Gemini" actions.

Why for Ionic

Mobile developers using Ionic frequently ask AI tools for help with Capacitor APIs, native plugins, platform-specific configuration, and lifecycle quirks. Right now the flow is: scroll the docs, manually select page content (avoiding nav and code-block UI), paste, then ask the question. With this plugin it's: click → "Open in Claude".

The plugin is currently shipping on Ethereum execution-apis, Sui (Mysten Labs), Walrus, Seal, SuiNS, Monad, Flare, Kaia, Nillion, Chronicle, and Cardano docs. Also listed in the official Docusaurus community plugins.

Changes

• Adds docusaurus-plugin-copy-page-button to dependencies in package.json (^0.4.2, alphabetical position next to existing docusaurus-plugin-* entries)
• Appends the plugin string to the plugins array in docusaurus.config.js

The button auto-injects into the table-of-contents sidebar. No further config required, theme-aware, mobile-friendly, ~5kb client.

Happy to revert or adjust if this doesn't fit the project's direction.

Thank you for the PR! While we aren't against adding this, the default positioning looks a bit off when you scroll up/down with the header: Preview

I tried adding some static positioning but it ends up looking like this:

I think this would look nice if we could statically position it in the header:

Or even in the side menu.

Thanks for the detailed screenshots. I pushed an update that avoids the default automatic placement entirely:\n\n- upgraded to docusaurus-plugin-copy-page-button@0.6.1\n- set injectButton: false so the plugin no longer injects into the ToC/header area automatically\n- render the public React component manually in the docs side menu on desktop\n- render an article-column fallback on mobile where the desktop side menu is hidden\n\nValidation I ran locally:\n- npm run build passes; it still reports the repo's existing broken-link/broken-anchor warnings\n- responsive Playwright smoke at 1440x900 and 390x850: desktop button is in the sidebar, mobile button is in the article, dropdown opens, and the dropdown stays inside the viewport
