CI cost control: disable automatic binary builds

- build.yml: manual-only (workflow_dispatch)
- build_and_release_template.yml: manual-only by default
- release.yml: confirmed tag-only trigger with warning

This prevents surprise build runner costs; run builds explicitly from Actions or by pushing tags.
