fix(release): make GHA cache export non-fatal and add manual dispatch

[mmols]

The v1.1.0 release job failed at the cache-export step with error writing layer blob: failed to reserve cache. The image had already built and pushed to ghcr.io, but the failed cache upload aborted the job before the chart was packaged/signed and the GitHub Release was created. I checked various quotas / limits and didn't see anything, so this looks transient.

• Add ignore-error=true to cache-to=type=gha.

  • A cache-export failure now warns instead of failing the release, since the cache upload is non-essential.

• Add a workflow_dispatch trigger.

  • Lets us re-run a release on demand (gh workflow run release.yaml -f version=vX.Y.Z). A plain job re-run replays the old workflow commit, so it wouldn't have picked this fix up.

To recover v1.1.0 after merge:

• delete the pushed images (already done)
• run gh workflow run release.yaml -f version=v1.1.0

📝 Walkthrough

Walkthrough

The release workflow now supports manual runs with a required release version input. It checks out and verifies the selected tag, prevents overwriting published releases, and ignores Docker Buildx cache export failures.

Changes

Release workflow

Layer / File(s)	Summary
Manual release and cache handling .github/workflows/release.yaml	Manual dispatch requires a string version input. The workflow checks out that tag. Docker Buildx cache exports use ignore-error=true.
Release existence and tag verification .github/workflows/release.yaml	The workflow stops when a published release already exists. Release creation requires the selected tag to pass --verify-tag.

Poem

I’m a rabbit by the build pipeline bright,
I enter a version and hop into flight.
Existing releases stay safe and sound,
Verified tags keep each hop bound.
Cache errors fade; the build goes on!

Merge Risk: 🟠 High · up to 7d24e

A manually supplied release version can execute unintended shell commands with the release token available, and transient or authentication errors during the release check can allow unsafe duplicate or incorrect release attempts. These current-head security and release-integrity risks should be fixed before merging.

set its ref from inputs.version when provided, falling back to github.ref_name,
so builds use the requested release tag.

manual version input and derived values through environment variables rather
than interpolating them into shell source, and quote all shell variable

release-tag format and that the tag exists, including in the steps that access

28-29: 🔒 Security & Privacy | 🔵 Trivial | 💤 Low value

Set persist-credentials: false as defense in depth.

The Dockerfile does not copy .git, and .helmignore excludes .git/, so the described artifact leak does not occur. Later steps use GH_TOKEN and do not require Git credentials.

In @.github/workflows/release.yaml:
- Around line 57-58: Update the release workflow’s version-resolution, Helm
packaging, and release-creation steps to pass steps.version.outputs.version
through the step environment and reference it only via a quoted shell variable,
eliminating direct interpolation into shell source; apply the same treatment to
the gh release view check and its error message.
- Around line 53-60: Update the “Refuse to overwrite a published release” step
to inspect the GitHub API response status, continuing only when the release
lookup explicitly returns 404 Not Found and failing for authentication,
rate-limit, transient, or other errors; preserve the existing failure when the
release exists. Add workflow concurrency keyed by inputs.version or
github.ref_name so simultaneous runs for the same version cannot pass preflight
together.
