ci(release): show the error body, retry the POST, and sweep for orphan tags
This file is the ancestor of installer's release.yml, and installer#22's
release run found two gaps in it the hard way: the run built every artifact,
pushed its tag, then took a 500 from POST /releases one second later and exited
22, leaving the tag orphaned with no binaries published.

link has not hit that, but it has the same two gaps verbatim.

`curl -sSf` prints no response body on an error status, so the only thing such
a failure leaves in the log is "curl: (22) ... error: 500" and the cause has to
be inferred from timestamps. Every call in the release step now captures the
body and prints it on failure, including the asset uploads.

And nothing retried, so a transient 5xx becomes a permanent orphan. The POST
now retries five times with a 5/10/15/20s backoff. 4xx is deliberately not
retried: a bad token or a malformed body will not improve by being sent again,
and retrying would turn a clear failure into a slow one.

The asset uploads get the same treatment, because a release whose SHA256SUMS
does not cover every binary it advertises is worse than no release -- that file
is the trust anchor for an unsigned download.

The third gap is the one worth reading. The orphan-tag recovery in the plan
step is VERSION-SCOPED: it computes VERSION from the newest tag plus the bump,
then only checks refs/tags/v${VERSION}. That recovers an orphan on the very
next run and is useless afterwards, because once any releasable commit lands
the next run computes a NEW version and never looks at the old tag again.

servuo-plugins v0.1.0 proves it, and the proof is pointed: the commit that
ADDED that recovery was itself typed "fix(release): ... recover the orphaned
v0.1.0 tag", so it bumped to v0.1.1 and the run that introduced the recovery
stepped straight past the tag it was written to rescue. That tag is orphaned to
this day.

So the plan step now sweeps every v* tag and warns about any without a release.
Deliberately warns rather than recovers: publishing an old version would mean
building today's tree and shipping it under a tag whose tree it is not, which
is worse than the inconsistency it fixes. It also never fails the run -- a
sweep that can break a good release is a sweep someone will delete.

Verified by extracting both steps from the YAML and running them: bash -n
clean, the YAML parses, no empty template token in either step, the retry loop
exercised against a stubbed curl across seven cases (first-try success,
500-then-success, two 500s then success, five 500s giving up, 403 and 404
aborting without retrying, and a 000 network failure retried), and the sweep
run against the real repositories -- link clean, servuo-plugins reporting
v0.1.0, installer clean.

Typed ci(...) rather than fix(...) on purpose: the plan step bumps on feat/fix,
and this changes no binary, so a release here would be an empty one. That is
the same rule the fix commit above tripped over.
