Initial release of research-claim-checker.

- Provides tools to assess whether research conclusions are supported by evidence and identify gaps in the evidence chain.
- Produces structured outputs: conclusions, corresponding evidence, gaps, required additional evidence, suggested revisions, and confidence assessments.
- Designed for research, claims, and evidence workflows; not for fabricating sources or replacing peer review.
- Includes explicit boundaries for safety, privacy, and compliance.
- Supports both script execution (if permitted) and direct text outputs using provided templates and specs.
