fix(lint): relocate Wave 0 JSON artifacts to docs/rebase/

The henxels allowed_filetypes rule polices top-level ./docs/* for
markdown/yaml only; machine-generated JSON artifacts are not docs.
Moving rebase-inventory.json and rebase-wave-coverage.json under
docs/rebase/ (outside the single-segment glob) rather than widening
the gate's except list to fit new files. All consumer references
updated (rebase_inventory.py, rebase_issue_factory.py, wave0 report).
