add docusaurus-plugin-copy-page-button

[portdeveloper]

adds docusaurus-plugin-copy-page-button — a "Copy page" button in the docs sidebar that exports the current page as clean markdown, with one-click "Open in ChatGPT / Claude / Gemini" actions.

useful for the contracts/SDK pages especially — when someone's on, say, a v4 hooks page or a SwapRouter reference and wants to ask claude "rewrite this for my use case", they can grab the page markdown in one click rather than copy/pasting around the page chrome.

complementary to docusaurus-plugin-llms that's already in here — llms.txt covers full-site discovery for AI tools, this covers per-page handoff for a human reader who wants to drop a single page into a chat. theme-aware, mobile friendly, auto-injects into the TOC sidebar, no config required.

already running on Arbitrum docs (similar docusaurus + ai-tooling setup) and ~12 other sites including Ethereum execution-apis, Sui, Monad, Flare, Kaia, Cardano. listed in Docusaurus community plugins.
