Fixed

-   Fix a crash seconds after launch on Intel Macs; cmux is now the only process-wide crash handler, and embedded GhosttyKit no longer links Ghostty's native Sentry initializer ([#9436](https://github.com/manaflow-ai/cmux/pull/9436))
-   Fix `cmux ssh <host>` failing immediately with a shell syntax error from the generated startup script ([#9425](https://github.com/manaflow-ai/cmux/pull/9425)) -- thanks @KousukeUchiyama for the report!
-   Clear Dock notifications when you focus the pane that raised them ([#9418](https://github.com/manaflow-ai/cmux/pull/9418))
-   Keep a restored Claude agent on its own account instead of falling back to the ambient one ([#9419](https://github.com/manaflow-ai/cmux/pull/9419)) -- thanks @seanyoungberg for the report!
-   Stop bash shell integration printing `cannot overwrite existing file` on every prompt under `set -o noclobber` ([#9420](https://github.com/manaflow-ai/cmux/pull/9420)) -- thanks @8bit-void for the report!
-   Fail closed when `close` or `respawn-pane` is given an explicit `--surface` that no longer exists, instead of acting on a different live surface ([#9422](https://github.com/manaflow-ai/cmux/pull/9422)) -- thanks @PhilipPinckaers for the report!
