Why would we not use `${command:pickProcess}`? Why bypass the regular command 
logic? We can already determine the `lldb-dap` path inside the command (also 
see https://github.com/llvm/llvm-project/pull/128943#discussion_r1976269198)

Note that we would also need to pass through parameters like 
`gdb-remote-hostname` and `gdb-remote-port` such that the `--list-processes` 
would reach out to the right gdb/lldbserver.

All in all, this sounds like a good long-term direction to me.

@matthewbastien I am not sure I understand that concern. Looking at the [commit 
log of 
swiftlang/llvm-project](https://github.com/swiftlang/llvm-project/commits/next/lldb/tools/lldb-dap),
 it seems that they are picking up changes to `lldb-dap` very quickly. Or am I 
missing something?
