De-brand shipped harness surface, rename config files, and add a standing portability gate.
Changes:
- Removed Flowser-specific prose from all shipped agent/skill/hook files (107 literals scrubbed)
- Renamed
.ck.json→.vc.jsonconfig with automatic legacy fallback so existing installs keep working - Added
validate-kit-portability.mjs— a survivor-allowlist gate that catches brand leaks and danglingprocess/context/refs on the kit surface between releases - Widened
vc-publishStep 8 leak scan to cover the full resolved text surface (not just CLAUDE.md/AGENTS.md) vc-publishnow creates a GitHub Release after every publish (this release)
