Programs inside the container (e.g. Claude Code's "hit c to copy") can now write to the host system clipboard. A shell script shim installed as xclip/xsel/pbcopy emits OSC 52 escape sequences, which the xterm.js frontend intercepts and forwards to navigator.clipboard.writeText().

# OSC 52 clipboard provider — sends clipboard data to the host system clipboard

# Supports common invocations:

# echo "text" | pbcopy
