"""Gitea CI monitoring script — checks latest run status and fetches failure logs.

Usage:
  python3 ci-status.py <repo_path> [--all-runs] [--run N] [--logs]

Requires: token file at <repo_path>/.gtb64 (base64-encoded, created via write_file tool
          to bypass Hermes secret redaction) or <repo_path>/.gtoken (plain text).
          Prefer .gtb64 — Hermes redacts plain-text token patterns in write_file.
