Tooling: Alibaba Cloud OSS distribution for Release assets

Release downloads no longer depend on GitHub's reachability alone (#166).

A new mirror-oss release job downloads the exact assets attached to the GitHub Release, re-verifies their checksums, and mirrors the same bytes to an Alibaba Cloud OSS bucket; latest.json is uploaded last and only after every asset landed, so the mirror never advertises a partially mirrored version. The job reads its provider/role ARNs and bucket settings from the oss-production environment and fails fast with a named error when one is missing.
install.sh / install.ps1 gain a download-source switch: PENGUIN_DOWNLOAD_SOURCE=auto (default) prefers the OSS mirror and falls back to the same version on GitHub when the mirror is unavailable; oss and github pin one source. PENGUIN_DOWNLOAD_BASE_URL / PENGUIN_DOWNLOAD_FALLBACK_BASE_URL override the asset directories directly (https-validated), and download progress names the source it is actually using.
An oss-staging workflow plus scripts/publish-release-to-oss.sh, scripts/install-ossutil.sh and scripts/test-oss-staging.sh exercise the mirror path end to end before production, and the hermetic installer tests cover the source switch on both platforms.
The installation docs document the download-source row for both languages.
