Maxwell MorrisandClaude Sonnet 5 110bd97cca Move to a three-node cluster with a Talos VIP; add Longhorn
Every node is now both control plane and worker, giving real tolerance
for losing any single machine (etcd quorum needs 3, not 1). A Talos VIP
gives the cluster one stable address regardless of which node answers.

Also pre-installs Longhorn for replicated storage, backed by a Talos
UserVolume on each node's second disk (>=900GB, non-system) rather than
the default path — mirroring the pattern from the homescale repo.

Docs renumbered to make room for 06-longhorn.md; checklist, glossary,
network map, and CLAUDE.md's guided-bootstrap instructions updated to
match, including asking the user for node IPs, VIP, and disk info before
generating any Talos config.

# An "umbrella" chart: it declares a dependency on the upstream MetalLB
# chart below, AND carries two templates of its own
# (apps/metallb/templates/) — the IPAddressPool and L2Advertisement that
# configure it. Argo CD detects this as a Helm source because a Chart.yaml
# exists at this path, resolves the dependency, and syncs the combined
# rendered output as one Application — exactly like any other app in
# apps/. This is the real, working example of the Helm-based app pattern
# mentioned in docs/08-adding-new-apps.md: use it as a template if you want
# to bring in another third-party chart later.
