Add Claude auto-fix to check_errors.py, distinguish LLM failure in Slack reports

- check_errors.py: on errors, call Claude CLI to diagnose and attempt auto-fix,
  include fix report in Slack alert
- slack_notifier.py: show "LLM 分析失敗" when LLM fails instead of "All HOLD"
- main.py: track llm_ok flag and pass to Slack reporter
- setup.sh: restore ~/.local/bin in crontab PATH for claude CLI
- llm_analyzer.py: use shutil.which for robust claude binary lookup
