v0.16.0

Added

• Response Playbook — turns AI next steps + Critical/High findings into a trackable checklist; optional IR-templates expansion (issue #36).
• Push the Playbook to DFIR-IRIS and to ClickUp (idempotent re-push).

Changed

• Every DFIR_* env var is now configurable from Settings.
• The Playbook takes the prominent dashboard slot; Recommended Next Steps is hidden by default.

Fixed

• Hunt-pivot VQL uses OSPath instead of the deprecated glob() FullPath.
