Add docusaurus-plugin-copy-page-button

[portdeveloper]

What this adds

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

Why for Puffer

The plugin is already shipping on most major DeFi/L1 docs sites: Ethereum execution-apis, Sui (Mysten Labs), Walrus, Seal, SuiNS, Monad, Flare, Kaia, Nillion, Chronicle, and Cardano. Restaking and preconf docs are exactly the kind of content devs paste into Claude or ChatGPT to ask "what would this contract integration look like" or "explain the slashing conditions in this validator setup."

Changes

• Adds docusaurus-plugin-copy-page-button to dependencies
• Adds the plugin string to the end of the plugins array in docusaurus.config.js

The button auto-injects into the table-of-contents sidebar across all your docs routes (yield, puffer-preconf, institutional). No further config required, theme-aware, mobile-friendly.

Friendly bump — happy to revise, rebase, or close this if it's not a fit for your project.

Quick update since I opened it: Cardano docs shipped the plugin (merged in input-output-hk/cardano-documentation#739), so it's now running in production on Ethereum execution-apis, Sui (Mysten Labs), Walrus, Seal, SuiNS, Monad, Flare, Kaia, Nillion, Chronicle, and Cardano. Also now listed in the official Docusaurus community plugins.

No worries if this isn't on your roadmap — just want to make sure it didn't slip through the cracks.

fyi shipped 0.5.2 today and pushed the version bump (^0.4.2 → ^0.5.2) on this branch.

the most relevant fix: the button now renders on pages without a ToC. previously the fallback was a fixed-position overlay in the top-right viewport corner which often got hidden behind navbars — easy to miss when reviewing a landing/index page. now it injects inline after the breadcrumbs.

also in 0.5.2: button + dropdown inherit --ifm-font-family-base (was browser default), min-height reserved on the container to reduce layout shift, and a MutationObserver replaces the chained setTimeout polling so the button shows up reliably on first render.

all credit to @Simek who reviewed facebook/react-native-website#5085 and flagged these.

happy to close this out if not a fit — just wanted to flag the fixes in case the no-ToC behavior was a blocker.
