Tyler 99c2acf90c fix(ci): bootstrap the reusable MinIO image in GHCR (#7869)
Upstream MinIO image pulls are blocking CI (#7867). Add a separate
publisher for `ghcr.io/block/buzz-minio:latest`, so the reusable image
can be bootstrapped before CI adopts it in #7870.

- Build the checksummed official MinIO/mc release binaries from #7868 on
a digest-pinned Alpine base.
- Build only when image/workflow/Compose inputs change or on manual
dispatch. PRs build and smoke-test; only `block/buzz` main can publish.
- Run the real Compose healthcheck and initializer, object
upload/read/delete, and anonymous-access denial before publishing
`latest` plus a unique `sha-<commit>-run-<id>-<attempt>` tag.
- Manual dispatch disables Docker's layer cache to refresh Alpine
packages. Normal image builds retain caching; each maintenance rebuild
keeps its own tag.

### Rollout

This PR contains only the publisher and opt-in Compose override. **It
does not switch ordinary CI consumers**, so its checks do not require
the unpublished image. This is a separate PR from adoption, as required
by Buzz's squash-only merge rules.

1. Merge this PR; its main-branch workflow builds, tests, and publishes
the image.
2. Make the `buzz-minio` GHCR package public and verify an anonymous
pull of `ghcr.io/block/buzz-minio:latest`. New GHCR packages default to
private.
3. Rebase draft #7870 onto current main, retarget it to main, run its
integration checks, and merge it to switch all MinIO-backed CI jobs to
the published image.

### Validation

- Updated hosted [MinIO image build and smoke
test](https://github.com/block/buzz/actions/runs/36018177877) passed at
`700ab6d5346b37a64c9defde0016dc65c98aa790`; publication correctly
skipped on the PR.
- Hosted [ordinary
CI](https://github.com/block/buzz/actions/runs/36018178123) passed at
the same head. Its actual Git comparison detected only the five
publisher files, all application path filters were false, and the
MinIO-dependent integration checks were correctly skipped. Synced
current main before this run to eliminate an earlier stale-base
comparison that included unrelated ACP changes.
- Actual five changed paths were passed through the repo's pinned
`dorny/paths-filter`: all application domains were false. All 12
existing path-selection cases and the required-context isolation
contract also passed.
- Publisher actionlint, smoke-script shellcheck, and commit/push hooks
passed.
- Fresh local rebuild of `700ab6d5346b37a64c9defde0016dc65c98aa790`
passed with `docker buildx build --no-cache --platform linux/amd64
--load`. Logs confirm new Alpine index fetches and package installation
rather than a cached install layer. The committed smoke script passed
under local AMD64 emulation using the current merged Compose services
with isolated resource names and no published ports: healthcheck,
initializer/private bucket, object upload/read/delete, and anonymous
HTTP 403. Temporary containers, network, and volume were removed. Both
pinned binary checksums match the official release SHA-256 files.
- Full `just ci` was previously attempted: workspace formatting/Clippy,
desktop checks, and Tauri formatting passed; the run was stopped during
Tauri Clippy. No full local application-suite pass is claimed; hosted
application suites correctly skip this publisher-only change.
