Clipboard

Gives Claude direct read/write access to your system clipboard through `clipboard_paste`, `clipboard_copy`, and related tools. The main win is preserving structure when you copy tabular data from spreadsheets: instead of pasting cells into chat as mangled text, you tell Claude to read your clipboard and it gets a proper Markdown table or JSON with columns intact. Also sidesteps Claude Code's terminal padding artifacts by writing clean commands straight to clipboard. On Linux it reads the PRIMARY selection buffer (middle-click paste) separately from the Ctrl+C clipboard, so you can highlight terminal errors or code selections and ask about them without clobbering what you already copied. Handles images, HTML, RTF, and arbitrary MIME types.
