Key hardening changes:
- Config validation now rejects paths.source: . and paths.assets: ., so source/asset roots cannot
resolve to the repository root.
- apply-hak-manifest now refuses to run when paths.source is unset or unsafe, instead of potentially
writing under a root-level module/.
- Inline flags across utility parsers now reject empty values consistently, e.g. --dataset=, --hak=,
--endpoint=, --output=.
- build-changelog now supports --flag=value inline syntax like the other utilities.
