v0.63.9

# The Release-Reliability Upgrade

This set of releases tightens up the shipping pipeline and keeps the release branch moving smoothly—so builds stay green and delivery stays fast. 🎉

## Highlights

### Release branch sync & conflict resolution 🔀
We kept `release` in lockstep with `main` through a series of promotions, ensuring the latest accumulated work lands cleanly where production builds are cut.

One promotion also required a careful conflict resolution pass to preserve the already-cut release versions while still bringing forward the full set of changes from `main`. ([#5203](https://github.com/tinyhumansai/openhuman/pull/5203), [#5242](https://github.com/tinyhumansai/openhuman/pull/5242), [#5256](https://github.com/tinyhumansai/openhuman/pull/5256)) — Thank you @M3gA-Mind!

### Linux AppImage release unblock 🐧
Linux desktop release smoke tests are back on track: an AppImage startup failure on Ubuntu 23.10+ was addressed by adjusting the user namespace sysctl behavior used during the release job, unblocking production runs. ([#5251](https://github.com/tinyhumansai/openhuman/pull/5251)) — Thank you @M3gA-Mind!
