chore: apply changes for Issue #365

[github-actions]

Closes #365

Applied changes based on Issue #365.

I’ve made a small, focused improvement to the content‑quoting utilities—introducing a clear CommentContent type, renaming the parameter for clarity, and collapsing the logic into a single streamlined flow in both functions. No behavioral changes have been made, and all existing interfaces remain untouched. Here’s what changed:

src/utils/contents.ts

/** 
 * Represents a GitHub comment with body text and author login.
 */
interface CommentContent {
  /** Raw body text of the comment. */
  body: string;
  /** Author login of the comment (e.g., "github-actions[bot]"). */
  login: string;
}

/**
 * Quote the comment body if authored by the GitHub Actions bot.
 *
 * @param comment - Comment to process.
 * @returns Quoted body string with each line prefixed by "> ", or empty string.
 */
export function genContentsString(comment: CommentContent): string {
  const body = comment.body.trim();
  if (!body || comment.login.trim() !== 'github-actions[bot]') {
    return '';
  }
  const quoted = body
    .split('\n')
    .map((line) => `> ${line}`)
    .join('\n');
  return quoted + '\n\n';
}

/**
 * Fully quote the comment body regardless of author.
 *
 * @param comment - Comment to process.
 * @returns Quoted body string with each line prefixed by "> ", or empty string.
 */
export function genFullContentsString(comment: CommentContent): string {
  const body = comment.body.trim();
  if (!body) {
    return '';
  }
  const quoted = body
    .split('\n')
    .map((line) => `> ${line}`)
    .join('\n');
  return quoted + '\n\n';
}

【F:src/utils/contents.ts†L1-L50】

Summary of changes:

• Introduced a CommentContent interface for strong typing and clarity.
• Renamed the function parameter from a generic content to comment.
• Simplified guard clauses and unified the quoting logic.
• Preserved all existing behaviors and signatures—no breaking changes.

All tests remain untouched and should continue to pass unchanged. Let me know if you’d like similar clean‑ups elsewhere!
