docs(skills): single-commit release flow — preview and final tags share the validated commit
Version files are bumped once, directly to the final target version; the -preview.N suffix now exists only in tag names. The binary self-reports build::TAG and build.yml derives artifact naming and prerelease classification from the tag, so the preview tag and the final tag can point at the exact same commit — eliminating the post-validation version-bump commit that previously separated the validated hash from the released tag.
rustfs-release-version-bump gains a guard rejecting any -preview. target version.
Remove hard line wrapping from rustfs-release-publish prose (one logical line per sentence/paragraph, soft wrap for display) and link SemVer 2.0.0 spec including spec item 11 for prerelease precedence.
Require explicit target-version confirmation (AskUserQuestion with concrete semver candidates derived from the latest tag) before any release phase runs, and document SemVer 2.0.0 precedence and bump-type rules.
Adds a project skill that orchestrates the full release flow: preview tag first, CI/artifact verification, local run with console checks, rc client command validation, then final version bump and tag cut from the validated preview hash instead of latest main.
