What

Replaces the bare pass/fail job summary with a structured Commit Check Policy Report that shows per-check results as a clean Markdown table.

Before (current)

# Commit-Check ❌
` `` (collapsed)
bad commit output here
` ``

After (this PR)

# Commit Check Policy Report

**Repository**: `owner/repo`
**Policy file**: `commit-check.toml`
**Trigger**: `pull_request`

| Check | Result |
|---|---|
| Commit message | ❌ Fail |
| Branch naming | ✅ Pass |

### ❌ Some checks failed

<details>
<summary>Details</summary>
...
</details>

Why

• Screenshot-ready: clean table format users can screenshot for READMEs, PR comments, compliance docs
• Per-check visibility: users immediately see which check failed instead of parsing raw logs
• Compliance/ODS alignment: structured policy report with repository info, policy file, and per-check status
• Zero breakage: run_commit_check() and add_pr_comments() are completely unchanged

How

• Leverages commit-check --format json for reliable per-check pass/fail determination
• On pass: shortcuts to all-pass results (no extra work)
• On failure: runs lightweight per-check JSON lookups to identify which exact checks failed
• Raw output preserved in a collapsible <details> section for diagnostics
• New CheckResult dataclass, build_policy_report(), determine_check_results(), and build_pass_results() functions
• 18 new tests (65 total, all passing)

Checklist

• All existing tests pass (47 unchanged)
• 18 new tests added for report functions
• Black / codespell / mypy clean
• result.txt and PR comment behavior unchanged
• job-summary: false still skips as before
