Added

• aigrd judge: one pass or fail per rubric criterion, with a quoted span
  as evidence and a fix note, from a second model run through the claude
  command-line tool.
• --harness claude: the Claude Code Stop-hook decision, with bounded
  attempts per session and file and a visible give-up.
• aigrd init, rubric derive, rubric check, rules and docs.
• aigrd hooks install, the 40-aigrd pre-commit fragment, and
  hooks claude.
• The run log .aigrd/runs.jsonl and aigrd runs; aigrd label, which
  writes portable evaluation cases beside the rubric; aigrd agreement.
• A verdict cache keyed on the file content, the rubric bytes and the
  judge command.
• [judge].max_thinking_tokens, a cap on extended thinking in the judge.
• Three example projects: an article, a landing page and an investment
  thesis, each with a rubric and a passing and a failing sample.
