* LLDB can now set breakpoints, show backtraces, and display variables when
debugging Wasm with supported runtimes (WAMR and V8).
* LLDB no longer stops processes by default when receiving SIGWINCH signals
(window resize events) on Linux. This is the default on other Unix platforms.
You can re-enable it using `process handle --notify=true --stop=true SIGWINCH`.
* The `show-progress` setting, which became a NOOP with the introduction of the
statusline, now defaults to off and controls using OSC escape codes to show a
native progress bar in supporting terminals like Ghostty and ConEmu.
