✨ Core v1.7 Enablement

- Add spec version selection end-to-end with a new --spec-version flag (default 1.7).
- Update JSON and XML outputs to honor the selected spec version.
- Update fixtures, help text, tests, and docs.

Files:
- lib/bom_helpers.rb:
  - Added SUPPORTED_SPEC_VERSIONS, cyclonedx_xml_namespace helper.
build_bom now accepts spec_version and routes to:
    - build_json_bom(gems, spec_version) sets specVersion to the provided version.
    - build_bom_xml(gems, spec_version) sets xmlns to http://cyclonedx.org/schema/bom/<version>.</version>
- lib/bom_builder.rb:
  - Added --spec-version with validation; default is 1.7.
  - Pass @spec_version into build_bom(@Gems, @bom_output_format, @spec_version).
