ci: add workflow_dispatch with tag input and pre-release tag logic

- workflow_dispatch accepts a `tag` input (e.g. v1.2.3 or v1.2.3-dev.1)
- build-release-* jobs now trigger on both tag push and workflow_dispatch
- manifest creation distinguishes stable (x.y.z) from pre-release:
  stable → latest, x, x.y, x.y.z
  pre-release → only the exact version tag
