fix: address self-evaluation review comments

- Clarify that agent-evaluator reads skills/agent-self-evaluation/SKILL.md directly
- Standardize on Conciseness terminology, including helper names
- Remove invalid Stop hook matcher and avoid unsupported command-expression matcher examples
- Add explicit hook-integration reference path in SKILL.md
- Add summary and self-check fields to evaluate.py output, template, and agent spec
- Refactor evaluate.py clarity and input parsing helpers
- Remove unused task parameter from check_completeness

Validation:
- python3 -m py_compile skills/agent-self-evaluation/scripts/evaluate.py
- evaluate.py high/low example smoke tests
- node scripts/ci/validate-agents.js
- node scripts/ci/validate-skills.js
- node scripts/ci/validate-hooks.js
- node scripts/ci/validate-no-personal-paths.js
