PR #53 — Continuous Compliance documentation

• README.md: Added Linting Enforcement, Continuous Compliance, and Requirements Traceability feature bullets; added [link-continuous-compliance] reference

PR #54 — macOS support + Agent Selection Guide

• .github/ISSUE_TEMPLATE/question.yml: New question/help issue template

• requirements.yaml: Added macos@TestName source filter comment; added SonarMark-Plt-MacOS requirement with matching test evidence
