fix: adds better remarks and descriptions

[Copilot]

Pull request overview

Updates the Cloud Custodian “resources detected” policy bundle to produce richer, more user-friendly remarks/descriptions and to support propagating a custom non-compliance message from the plugin payload into the evidence description.

Changes:

• Enhance violation remarks and overall remarks aggregation, including execution exit code and better error-detail selection.
• Add support for raw_policy.non_compliance_message and append it to the generated description when non-compliant.
• Expand rego tests to cover new message formatting and additional execution-error/stderr scenarios; document the new payload field in README.
