fix(release): retry uploads with backoff + drop Gitea workflows

Gitea/nginx intermittently returns 504 on large multipart uploads even
when curl successfully streamed the body. Add up to 4 retries with
exponential backoff (15s/45s/2m/5m). Before each retry, check whether
the asset is actually present server-side at the expected size — Gitea
sometimes accepts the body but times out the response, so the file is
already there.

Also drop .gitea/workflows/* — we use release.ps1 locally and Gitea
Actions runners are not configured, so every push was leaving queued/
failed workflow runs in the Actions tab.
