svlens v0.3.6 — release-pipeline patch over v0.3.5

Fixes the last Node 20 deprecation surface
(softprops/action-gh-release@v2 -> @V3) and switches the GitHub
Releases body to the curated docs/releases/v<tag>.md so the release
page is no longer effectively empty for direct-push workflows.

svlens v0.3.5 — release-hygiene patch over v0.3.4

Republishes the v0.3.4 surface with the contract-test banner pinning
folded into the bump commit (see commit 0d5d6f6). No source-code
changes vs. v0.3.4.
