  • Fixes fallback to browser WebSocket in Node.js environment

• Add handleOsc52Command() for set/query/clear clipboard operations

• Register OSC 52 handler in TermWrap constructor

• Support base64 encoding/decoding for clipboard data

• Add error handling for clipboard access failures

Walkthrough

The changes introduce a new function, handleOsc52Command, in the terminal wrapper module to handle OSC 52 terminal escape sequences for clipboard operations. The function processes clipboard clear, query, and set actions, integrating with the system clipboard and encoding/decoding data as needed. The TermWrap class constructor is updated to register this handler with the terminal parser. Separately, in the WebSocket utility module, the asynchronous dynamic import of the "ws" module for Node.js is replaced with a synchronous require call within a try-catch block to address timing issues. No exported interfaces are changed in the WebSocket utility.
