035678da48 ⏫ Bump up Helm and Cilium; fix kubectl apply -f- 
On some versions of pssh, if we use kubectl apply -f- but
nothing is connected to stdin, we get errors. So execute
cat instead of kubectl apply -f- when needed.

c1971aa30b 🏭️ Replace Weave with Cilium 
Initially we were using Weave because it was super easy to
install (single kubectl apply -f command), but we now have
multiple problems:
- it is not maintained anymore
- its network policy controller seems to have subtle bugs
  (I had multiple classes in 2026 where we ran into policies
  that didn't work as intended, but worked fine when trying
  on another cluster that used Cilium)
- it doesn't support IPV6

We did a test run with Cilium on a few IPv6-only clusters.
It worked fine. Then a test run on dual stack clusters.
Now we're using Cilium on all kubeadm clusters (removing
support for Weave) and we've updated all materials to
either remove or update mentions to Weave.

528f687898 ♻️ Update konk machine type 
vcluster deployment mode needs 2 volumes per cluster (one for the
control plane, one for shpod), so we're switching to a smaller
machine type since that's quickly becoming the limiting factor
rather than CPU/RAM.

fb9e531c63 🔧 Fix Mermaid invocation 
It look like commit f9d73c0 introduced a very subtle regression
by removing what seemed to be an extraneous space in a selector...
But the space was there on purpose, so it had actually broken
Mermaid integration. This fixes it, hopefully in a way that won't
be affected the same way!

8ba96380b7 🔧 Disable threading in flask debug server 
For educational purposes, the RNG service is meant to
process only one request at a time (without concurrency).
But the flask server now defaults to a multi-threaded
implementation, which defeats our original purpose.
So here we disable threading to restore the original
behavior.

302924db40 🔧 Bump up vcluster version to work around weird bug 
(Probably due to K8S version mismatch; vcluster was on 1.33 and the
host cluster was on 1.35. Symptoms: some pods start, all their
containers are ready, the pod shows up as ready, and yet, it's not
considered ready so the deployment says 0/1 and Helm never completes.)
