Bump VERSION to 2026.10.26.1 and date its CHANGELOG.md entry: the
noVNC cache fix from cf4f5be.

The desktop failed to start in a browser that had cached noVNC 1.6
from the Debian desktop image: its vnc.html, which has no clipboard
Clear button, ran the Ubuntu image's 1.3 ui.js, which wires one up
and threw "Cannot read properties of null". websockify sends only
Last-Modified, so browsers cache noVNC on a guess, and it answers a
revalidation with 304 when the file on disk is older than the copy.
Serve noVNC through websockify-no-store, which adds Cache-Control:
no-store to every response, and from /novnc/ rather than /, so no
browser holds a stale copy at the paths the desktop now uses.

The release reaches main on 2026-10-21, when feat/lessons is merged:
replace the Unreleased heading with the version and that date, and
name the commits its entries came in.

Q103 failed to seed once in an audit of six hosts at a time: a minute
passed without a Falco alert naming the Pod. When that happens, the
setup now replaces the Pod - a new container, which Falco's container
plugin looks up afresh - and waits one minute more before it gives up.
Record the final audit in README.md and CHANGELOG.md: CKS 110/110 on
v1.37, Q103 passing alone and with the other seven VM tasks six at a
time, and CKA Q132, CKAD Q1 and CKS Q60, Q61 and Q64 passing on the
images rebuilt with hexdump and xxd.

Add lessons: untimed guided labs, one per curriculum objective, on a
host of their own, in the browser and in the terminal. Each step has
a check, a hint and its commands; a lesson writes no history or
scores, only a done mark on its objective. CKAD 2.1-2.4 (24 steps)
and all 27 CKA objectives (135 steps) have one, and `./ksim lesson
audit` proves that every step fails, is done by its own commands,
then passes.
Add CKA tasks 132-147 (cka/bank_course.py) on what a full CKA course
teaches beyond the bank: a real upgrade from v1.36, a drain under a
PodDisruptionBudget, QoS and eviction, in-place resize, kube-proxy's
chains, encryption at rest, an operator, and CSI expansion, snapshots
and clones (ensure_csi_hostpath).
Move CKA and CKS to Kubernetes v1.37 and rebuild the hosts on Ubuntu
24.04, with kubelet, kubeadm and kubectl as held packages from
pkgs.k8s.io; the desktop runs Ubuntu too. Hosts gain man pages,
hexdump and xxd.
Fix CKS Q4, which gave 3 of 12 points untouched, and CKA Q4 and Q49,
whose solutions raced their new CRD.
Audited on v1.37: CKA 147/147, CKAD 105/105, CKS 109/110 (Q103, a
Falco task, failed to seed once and awaits a re-audit); lessons: 135
of 135 CKA steps and 24 of 24 CKAD steps.

Add a changelog from the first release (2026.10.12.1) up to
2026.10.15.3, newest first, with Added/Changed/Removed/Fixed sections
and the commit behind each entry. List dark mode under 2026.10.15.3,
since it shipped without a version bump.
