feat: add audit-project SKILL.md

[avifenesh]

Summary

Add `skills/audit-project/SKILL.md` so the file-based skill referenced by agentsys's Code Review category actually exists in this repo.

Why

Workspace audit surfaced that agentsys's Skills table lists `audit-project` under Code Review but the plugin had no SKILL.md - only commands. Rather than drop the listing (which reflects a real invocable workflow), adding the file so the 40-skills ecosystem claim is accurate.

Contents

• Standard SKILL.md frontmatter with trigger phrases ("review my code", "audit the codebase", "security review", etc.)
• Documents the 8-phase workflow by delegation to `commands/audit-project.md`
• Lists all 10 role-based reviewers and severity classification
• Pure documentation of existing behavior - no code changes

Test plan

• agnix validation passes (frontmatter schema correct)
• Trigger phrases cover the user-invocation patterns
• No new dependencies or workflow

---

Note

Low Risk
Low risk documentation-only change that adds a new skill descriptor file without modifying runtime code or workflows.

Overview
Adds a new skills/audit-project/SKILL.md file so the audit-project skill exists as a file-based entry.

The document defines trigger phrases, arguments, and a high-level description of the existing 8-phase /audit-project workflow, including the reviewer roles and severity classification, and links to the corresponding commands/ docs.

Code Review

This pull request introduces the audit-project skill, which provides a multi-agent iterative code review workflow. The documentation outlines the tool's behavior, including agent selection, severity classification, and the iteration loop. Feedback focuses on maintaining consistency in the naming of specialized reviewers throughout the document to align with the defined role names.
