ci(release): skip pre-release tags (tag-only for -rc/-alpha/-beta)

Guard the release job so only FINAL version tags (v2.0.0) build + publish a
GitHub Release; pre-release tags (containing '-') are tag-only, leaving Latest
unchanged — matching the v2 pre-release strategy (alpha/rc = pinnable tags, not
Releases). Manual workflow_dispatch still runs.
