ZDDC 55852a9efb helm: add zddc-server-cache example chart + ZDDC_NO_AUTH on prod/dev
New chart helm/zddc-server-cache/ deploys zddc-server in client mode
against an upstream master. Mirrors the prod chart's source-build-via-
init-container pattern but with:

- ZDDC_UPSTREAM, ZDDC_MODE, ZDDC_BEARER_FILE, ZDDC_NO_AUTH,
  ZDDC_SKIP_TLS_VERIFY, ZDDC_MIRROR_SUBTREE, ZDDC_MIRROR_MIN_INTERVAL
  wired from values.yaml. Mirror-only env vars conditionally rendered
  (only when mode=mirror) to keep the rendered manifest minimal.
- Bearer token mounted from a separately-created Kubernetes Secret
  (defaultMode 0400) at /etc/zddc/bearer/token. values.yaml.example
  documents the secret-creation flow but contains no token. Secret
  reference can be set to "" to disable bearer auth (only valid for
  upstreams running --no-auth).
- Recreate strategy + replicaCount: 1 (multiple replicas would race
  the cache directory and double the upstream walker traffic).
- TCP-socket probes instead of HTTP — HTTP probes against / would
  fail when both upstream is unreachable AND the cache is empty
  (the cache layer returns 503 + offline header in that state),
  causing crashloops. TCP verifies process liveness without depending
  on upstream reachability or cache contents.
- Mounts a separate cache PVC (operator-provided, like the master's
  data PVC). Sized to the working set you expect to mirror; can be
  much smaller than the master's data volume.

Existing prod and dev charts gain optional ZDDC_NO_AUTH wired from
zddc.env.noAuth (default false → no change to existing rendered
manifests). Useful for trusted-LAN or genuinely-public master
deployments.

Updated docs: helm/README.md gains the cache row in the chart table,
the cache-install quickstart with the secret-creation flow, and the
cache-specific structural notes (Recreate / TCP probes / single-
instance). CLAUDE.md and ARCHITECTURE.md updated to reflect three
charts instead of two.

Verified with helm template rendering: ZDDC_NO_AUTH only renders
when noAuth: true; ZDDC_MIRROR_SUBTREE / ZDDC_MIRROR_MIN_INTERVAL
only render when mode: mirror; bearer volume + ZDDC_BEARER_FILE
only render when bearer.secretName is non-empty.
