👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs.

심볼릭 링크 디렉토리 순회 누락 회귀가 발생합니다.
Line 32에서 entry.isDirectory()만 검사하면 디렉토리 심볼릭 링크를 재귀 순회하지 않습니다. 기존 statSync(path).isDirectory() 기반 동작과 달라져, 링크된 하위 트리의 .md 파일이 누락될 수 있습니다(예: listUseCases, doctor 대상 해석 경로).
수정 제안 (성능 이점 유지 + 링크 디렉토리만 폴백 stat)
for (const entry of readdirSync(root, { withFileTypes: true })) {
const path = join(root, entry.name);
- if (entry.isDirectory()) files.push(...walkFiles(path, predicate));
+ const isDir = entry.isDirectory() || (entry.isSymbolicLink() && statSync(path).isDirectory());
+ if (isDir) files.push(...walkFiles(path, predicate));
else if (predicate(path)) files.push(path);

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

💡 What:
src/files.ts내부의walkFiles함수가readdirSync호출 시{ withFileTypes: true }옵션을 사용하도록 개선했습니다.🎯 Why: 기존 코드는 파일 트리를 순회하면서 디렉토리 여부를 판단하기 위해 모든 항목에 대해 개별적으로
statSync를 호출하여 I/O 병목 현상을 유발하고 있었습니다.Dirent객체를 반환받으면 이 문제를 근본적으로 피할 수 있습니다.📊 Impact: 디렉토리 트리를 순회할 때 발생하는 디스크 I/O 작업(특히
statSync호출)을 절반 이상 줄여 전체 탐색 성능을 크게 향상시킵니다.🔬 Measurement:
