v1.0.0-rc.135 (#44)

This is an UNSTABLE release. The release has significant modifications and bug fixes, if things go wrong, it is better to revert to 1.0.0-rc.132.

* Multiple small bug fixes scattered across the whole code base. (detected with GPT-5.4)
* jfjoch_viewer: Improve image render performance
