fix(security): unify secret redaction in public comment outputs (#1693)

Ensure all public issue, PR, and inline comments apply redactSecrets() in addition to sanitizeContent() before submitting payloads to the GitHub API. This aligns public comment output with error log and step-summary redaction policies, preventing potential leakage of Anthropic API keys, AWS credentials, Slack tokens, JWTs, and GitHub tokens.
