chore(release): irtt-server 0.5.2, irtt-rs 0.6.2

irtt-server's hex-pattern chunking moves to the stable as_chunks API
with no behavior change. irtt-rs picks up IRTT_SERVER_* environment
variable configuration, SIGTERM handling via ctrlc's termination
feature, and the Dockerfile/Gitea Actions pipeline that publishes its
server image to Gitea and GHCR.
