feat: render a warned rule as a warning, not a failure

[shenxianpeng]

What

commit-check/commit-check#565 lets a rule be listed under the config's top-level warn: it still runs, but the CLI reports it as "status": "warn" and never fails the run. This wires that status through the action's three output surfaces.

Behaviour

A warned scope gets:

• its own row in a new Warnings table (| Scope | Checked value | Warnings |), alongside the existing Failed checks table
• its own ⚠ line in the step log and the Markdown details block, with the same value/error/suggestion/docs layout a failure gets
• a ::warning annotation in the step log rather than ::error

It never turns the workflow red — a warned scope counts toward "passed":

✅ **3 of 4 checks passed**, 1 warning

A real failure still fails the run even when a warning sits in the same scope (CC202 stands in for branch when the two disagree), and the verdict then names both:

❌ **1 of 2 checks failed**, 1 warning

How

• ScopeResult.status gains "warn" (fail > warn > skip > pass, same priority as the App and CLI); new .warnings property alongside the existing .failures.
• overall_status / exit_code_for already fell through a warn scope to "pass" — documented, not changed.
• _render_scopes gets a warn branch; the failure/warning detail-line rendering was factored into a shared _render_findings so the two stay in sync.
• render_step_log's single annotations list is split into errors (::error) and warnings (::warning); the friendly one-line verdict now names warnings the same way it already names skips.
• _markdown_table takes a status/header pair (defaults keep the existing failure-table call sites unchanged) so the same function renders both tables.
• render_report extends the verdict and adds the Warnings table when there's anything to warn about.

Tests

13 new tests (TestWarnedScopes) covering status precedence in a mixed scope, the warnings property, overall_status/exit_code_for, a pinned golden warning-only report, warning+skip title ordering, failure+warning together (both tables, verdict names both), and the step log's ::warning annotation and friendly line. Full suite: 127 passed (up from 116). pre-commit (black, mypy, codespell) clean.

README documents the new warn config key and adds a "Warning Job Summary" section next to the existing Success/Failure/Skipped ones.

📝 Walkthrough

Walkthrough

The action adds a warn status, preserves failure precedence, renders warnings in logs and reports, documents warning configuration, and adds tests for status, exit codes, annotations, counts, and Markdown output.

Changes

Warning status support

Layer / File(s)	Summary
Warning status contract main.py, main_test.py	ScopeResult exposes warned checks. Failures outrank warnings, warnings outrank skips, and warnings do not fail the workflow.
Scope and step-log rendering main.py, main_test.py	Scope details use warning markers. Step logs emit ::warning annotations and report warning and skipped counts.
Report and documentation output main.py, README.md, main_test.py	Reports include warning tables and warning-aware verdicts. Documentation covers warn configuration and warning job summaries. Tests validate the rendered output.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 55f4e

When a scope has both failures and warnings, Markdown reports can omit the warning information even though workflow logs show warning annotations. This makes report output incomplete and inconsistent until mixed-status rendering is corrected.
