We have:

But it fails right now after reload because the command.id differs since it's created once for the renderer and once for the ptyHost here:

Haven't thought it through fully, but here's another idea for associating the tool call with the command which may end up being simpler:

• Only support linking commands for rich command detection
• In prepare, create the command ID manually via tool-${generateUuid()} and set on toolSpecificData, this would make serialize of the part just work at long as we restore the custom command ID
• In invoke, pass that command ID into runCommand
• Tell the pty host and renderer shell integration addon that the next command with the matching command line is the ID we created
