ci: add Release workflow triggered by v* tags

Pushing a tag matching v* now creates / updates a GitHub release with install.sh and install.ps1 attached, plus auto-generated changelog (commit log between prev and current tag) and standard install snippets in the body. Idempotent: re-pushing a tag updates the existing release rather than failing. For routine patch releases this replaces the manual `gh release create` flow. For larger releases that need a hand-written narrative, you can still overwrite the body via `gh release edit` afterward.
