Lunny Xiao 94ab020204 ci: mirror release artifacts to Cloudflare R2 (#1114)
Mirrors every release artifact into Cloudflare R2 alongside the existing AWS S3
upload, so both buckets carry the same objects during a parallel period. S3 is
untouched and stays authoritative for now; once R2 is confirmed complete it can
be dropped by deleting the `blobs:` block and pointing this at R2 alone.

### Why `publishers:` and not a second `blobs:` entry

goreleaser's blob pipe authenticates from the global `AWS_*` environment and has
no per-entry credential fields, so two different credential sets (AWS S3 and
Cloudflare R2) cannot coexist in `blobs:`. Custom publishers do support
per-entry `env:`, which is the supported way to isolate the two.

### Why `curl --aws-sigv4` and not `aws`/`rclone`

The CI image `docker.gitea.com/runner-images:ubuntu-latest` ships none of `aws`,
`rclone`, `s3cmd` or `mc`, but does ship curl 8.5 with `--aws-sigv4`. This keeps
the change zero-install. Credentials are fed to curl through a config file on
stdin rather than argv, so they never appear in the process list.

### Behaviour

- Object layout is identical to S3 (`gitea-runner/<version>/<artifact>`), so
  migrating consumers later means changing only the host, not the path.
- Nightly gets R2 too, matching the existing nightly-to-S3 behaviour.
- Missing R2 configuration fails the build. Because custom publishers run as the
  very last step of the publish pipeline, a preflight `--check-config` step runs
  right after checkout so the failure happens before anything is built or
  published rather than after the release already exists.
- Verified against a local MinIO instance (site region `auto`, matching R2):
  successful upload byte-compared after download, plus the missing-variable,
  wrong-credentials, missing-file and bad-argument paths.

### Required repository secrets

These must be configured before the next release run, otherwise the new
preflight step will fail the workflow:

- `R2_ENDPOINT` (full base URL, e.g. `https://<account>.r2.cloudflarestorage.com`)
- `R2_BUCKET`
- `R2_ACCESS_KEY_ID`
- `R2_SECRET_ACCESS_KEY`

### Known, deliberate wart

The publisher runs 109 times for 73 distinct object keys: goreleaser's release
pipe already registers `release.extra_files` as `UploadableFile` artifacts, and
`internal/exec` appends the publisher's own `extra_files` on top with no
de-duplication. It cannot be globbed away because `gobwas/glob` has no
substring-exclusion matcher, so `./**.sha256` cannot be narrowed to exclude
`*.xz.sha256`. It is harmless since PUT is idempotent, and the redundant
`./**.xz` glob is kept on purpose so the publisher declares its own complete
file set instead of implicitly depending on the `release:` block's globs. This
is documented in a comment above the block.

# Mirrors the S3 `blobs:` upload above into Cloudflare R2 during the
