GroundGuard v0.1.4

GroundGuard v0.1.4

This release implements the first phase of REFACTOR.md: precise claim span
offsets. The goal is to make downstream highlighting and text operations more
reliable without changing the public high-level APIs.

Added

• OutputClaim.start and OutputClaim.end offsets.
• Span offsets in assertion JSON claim objects.
• REFACTOR.md roadmap committed with an execution-status audit.

Changed

• Unverified claim stripping now uses span offsets when available, so repeated
  text spans do not cause the wrong occurrence to be removed.
• README installation and GitHub Action examples now point to v0.1.4.
