⭐ feat(runner): Fixes and improvements (#259)

## Description

- Improves latency for runner
- Fixes bugs in entrypoint bash scripts
- Package updates, gstreamer 1.26 and workaround for it

Modified runner workflow to hopefully pull latest cachyos base image on
nightlies. This will cause a full build but for nightlies should be
fine?

Also removed the duplicate key-down workaround as we've enabled ordered
datachannels now. Increased retransmit to 2 from 0 to see if it'll help
with some network issues.

Marked as draft as I need to do bug testing still, I'll do it after
fever calms down 😅
