Subject: [PATCH] chore: add missing ASF license headers

Adds the standard ASF header to the source files that were added after
the bulk header pass in July (PR 242) without one:

- cli/internal/plugin/*.go (5 files)
- converters/sigma/** Python sources, tests and pyproject.toml (15 files)
- converters/nvidia/tests/fixtures/*.yaml (2 files)

Header text and comment style follow the existing files in each
directory. No functional change.
