kernel-v0.1.1

Added

• Schema Validation Gate: scripts/validate_schemas.py with 5-check CI job (well-formed Draft 2020-12, unique $id, filename alignment, dangling $ref detection, $schema declaration).
• Fleet-wide OPSEC pre-push hook now tracked in notes repo (false-positive fix for docs/cookbook/ regex-pattern docs).

Fixed

• Declared missing third-party dependencies (pydantic-settings, jsonschema, pyyaml) in pyproject.toml that caused import failures in fresh venvs.
