Initial release of prompt-leak-auditor.

- Audits prompts and skill documentation for leaks of secrets, paths, internal rules, or high-risk instructions.
- Designed for use in prompt, security, and audit workflows.
- Provides a structured output covering scan scope, suspected leaks, high-risk patterns, remediation suggestions, review points, and follow-up actions.
- Enforces strict boundaries: does not re-output detected secrets, avoids sharing exploit steps, and requires clear user confirmation before any risky actions.
- Includes support for both script-based and manual audit methods depending on the environment.
- Masks sensitive content by default and prioritizes transparency and auditability.
