feat: enforcement and intent assessor improvements (ADR A.5, A.8) (#484)

* feat: enforcement and intent assessor improvements (ADR A.5, A.8)

Reprioritize DeterministicEnforcementAssessor scoring so agent hooks
(60 pts) outrank bypassable git hooks (40 pts), and add design doc
enforcement detection to DesignIntentAssessor (advisory 10 pts,
deterministic 15 pts). Also adds recommended starter hooks to
.claude/settings.json and updates test-assess skill cleanup to
avoid triggering the new destructive-command blocker.

* chore: add .agents/ and .codex/ to .gitignore

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: address CodeRabbit feedback on enforcement assessors

- Require non-empty hook entries before awarding 60 pts (not just key presence)
- Require both design-doc reference AND enforcement verb for deterministic bonus
- Fix remediation example to use correct nested hook schema
- Isolate agent vs pre-commit scoring test with separate repo paths
- Add negative test for hooks mentioning design docs without enforcement verbs

 #### Why It Matters
 
-Pre-commit hooks give immediate local feedback. They can be bypassed with `--no-verify`, which is why CI matters too — but for agent-generated commits that go through a normal PR flow, hooks are the first line of defense. Catching a lint error before a commit beats catching it in CI review.
+Agent hooks (`.claude/settings.json`) are deterministic for agent workflows: they always execute and cannot be bypassed. Git hooks (pre-commit, Husky) provide local feedback but can be bypassed with `--no-verify`. Both matter, but agent hooks score higher because they are the primary enforcement mechanism for AI-assisted development.
 
 #### Measurable Criteria
 
 The assessor scores on a 100-point scale:
 
-- **`.pre-commit-config.yaml` present** (60 pts): pre-commit hooks configured
-- **`.husky` directory with hook scripts** (60 pts): Husky git hooks configured (e.g., pre-commit, commit-msg)
+- **`.claude/settings.json` with hooks** (60 pts): Deterministic agent hooks configured (cannot be bypassed)
+- **`.pre-commit-config.yaml` present** (40 pts): Pre-commit git hooks configured (bypassable with `--no-verify`)
+- **`.husky` directory with hook scripts** (40 pts): Husky git hooks configured (bypassable with `--no-verify`)
+- **`.claude/settings.json` without hooks** (10 pts): Agent settings present but no hooks defined
 - **`.husky` directory without hook scripts** (10 pts): Husky directory exists but no hooks defined
-- **`.claude/settings.json` with hooks** (30 pts): Claude Code hook configuration present
 
-**Pass threshold**: 60 points or higher. Either `.pre-commit-config.yaml` or `.husky` with hook scripts is sufficient to pass.
+**Pass threshold**: 40 points or higher. Any single enforcement mechanism (agent hooks, pre-commit, or Husky with scripts) is sufficient to pass.
