Ports home-operations/tuppr#414 + home-operations/tuppr#415 to miroir.

charts/miroir/Chart.yaml carried a 0.0.1 placeholder, so the in-repo chart never
showed the version it corresponds to; only the release workflow's
helm package --version/--app-version gave the published artifact a real one.
release-please now stamps version/appVersion (current release: 0.11.10), and the
release workflow still re-stamps at package time, so the committed copy simply stops
going stale.

Why the typed generic updater

Chart.yaml is registered as {"type": "generic"} in extra-files rather than a bare
path. release-please picks its updater from the file extension, and the YAML updater
re-serializes the document: every comment in Chart.yaml would be dropped, and
appVersion would not be stamped at all. The generic updater only rewrites the semver
on lines annotated with x-release-please-version.

Consequences

• README.md.gotmpl drops chart.badgesSection for hand-rolled badges. The generic
  updater replaces only the first semver on an annotated line, and the shields.io
  badge/AppVersion-1.2.3-informational path form would let it swallow
  -informational as a prerelease suffix. The static/v1 query form terminates the
  version with &, keeps the version out of the alt text, and each version badge
  carries its own annotation, so the committed README stays in sync with the stamped
  Chart.yaml.
• Chart tests that hardcoded the placeholder now assert shape instead of a version:
  the controller and agent image tags, the --gateway-image= controller flag, and the
  helm.sh/chart label. They no longer need editing on every release. The
  default-gateway ("withholds the gateway args") case became notExists on a filtered
  path, because a notContains against a hardcoded tag would silently pass whether or
  not the flag was emitted.

Nothing about the published artifact changes: helm package in .github/workflows/release.yaml
and the e2e harness both pass --version/--app-version explicitly, and every image
tag in e2e is set explicitly too.

Verification

Gate	Result
mise run helm-lint	pass (1 chart(s) linted, 0 chart(s) failed; pre-existing icon is recommended info)
mise run helm-test (helm-unittest)	pass: 11/11 suites, 119/119 tests
mise run helm-docs-check	pass (no diff in charts/*/README.md, charts/*/values.schema.json)
oxfmt --check on the touched JSON/YAML	pass
lefthook pre-commit (format-json, format-yaml, helm-docs)	pass, no restaging

The two rewritten gateway assertions were checked for vacuity by inverting them
(notExists with the gateway enabled, and a deliberately wrong pattern); both failed as
expected before being finalized. No Go code is touched, so the Go gates are unaffected.

Greptile Summary

This PR keeps the in-repository Helm chart metadata synchronized with releases.

• Registers Chart.yaml and the generated chart README as release-please extra files.
• Adds release annotations to the chart version, app version, and README badges.
• Replaces generated badges with updater-compatible static badges.
• Makes Helm tests validate version-derived output without hardcoding a specific release.

Confidence Score: 5/5

The PR appears safe to merge, with release stamping, generated documentation, and version-derived Helm output remaining consistently wired.

The configured updaters target each annotated version independently, published packages still receive explicit chart and application versions, and the revised tests continue to validate the relevant rendered output.
