feat(skills): Add quality-audit-workflow skill for comprehensive codebase audits

This skill orchestrates a 6-phase quality audit workflow:
- Phase 1: Project Familiarization (investigation)
- Phase 2: Parallel Quality Audit (multiple agents per division)
- Phase 3: Issue Assembly (GitHub issues for findings)
- Phase 4: Parallel PR Generation (worktree per issue)
- Phase 5: PM Review (prioritization and grouping)
- Phase 6: Master Report (consolidated recommendations)

Features:
- Auto-activates on quality audit keywords
- Configurable parallel limit (default: 8)
- Progressive disclosure with reference.md and examples.md
- Follows Anthropic skill best practices

+# Quality Audit Workflow
+
+## Purpose
+
+Orchestrates a systematic, parallel quality audit of any codebase with automated remediation through PR generation and PM-prioritized recommendations.
+
+## When I Activate
+
+I automatically load when you mention:
+
+- "quality audit" or "code audit"
+- "codebase review" or "full code review"
+- "refactoring opportunities" or "technical debt audit"
+- "module quality check" or "architecture review"
+- "parallel analysis" with multiple agents
+
+## What I Do
+
+Execute a 6-phase workflow that:
+
+1. **Familiarizes** with the project (investigation phase)
+2. **Audits** using parallel agents across codebase divisions
+3. **Creates** GitHub issues for each discovered problem
+4. **Generates** PRs in parallel worktrees per issue
+5. **Reviews** PRs with PM architect for prioritization
+6. **Reports** consolidated recommendations in master issue
+
+## Quick Start
+
+```
+User: "Run a quality audit on this codebase"
+Skill: *activates automatically*
+       "Beginning quality audit workflow..."
+```
+
+## The 6 Phases
+
+### Phase 1: Project Familiarization
+
+- Run investigation workflow on project structure
+- Map modules, dependencies, and entry points
+- Understand existing patterns and architecture
+
+### Phase 2: Parallel Quality Audit
+
+- Divide codebase into logical sections
+- Deploy multiple agent types per section (analyzer, reviewer, security, optimizer)
+- Apply PHILOSOPHY.md standards ruthlessly
+- Check module size, complexity, single responsibility
+
+### Phase 3: Issue Assembly
+
+- Create GitHub issue for each finding
+- Include severity, location, recommendation
+- Tag with appropriate labels
+
+### Phase 4: Parallel PR Generation
+
+- Create worktree per issue (`worktrees/fix-issue-XXX`)
+- Run DEFAULT_WORKFLOW.md in each worktree
+- Generate fix PR for each issue
+
+### Phase 5: PM Review
+
+- Invoke pm-architect skill
+- Group PRs by category and priority
+- Identify dependencies between fixes
+
+### Phase 6: Master Report
+
+- Create master GitHub issue
+- Link all related issues and PRs
+- Prioritized action plan with recommendations
+
+## Philosophy Enforcement
+
+This workflow ruthlessly applies:
+
+- **Ruthless Simplicity**: Flag over-engineered modules
+- **Module Size Limits**: Target <300 LOC per module
+- **Single Responsibility**: One purpose per brick
+- **Zero-BS**: No stubs, no TODOs, no dead code
+
+## Navigation Guide
+
+### When to Read Supporting Files
+
+**reference.md** - Read when you need:
+
+- Detailed phase execution steps
+- Agent-to-phase mappings
+- Codebase division strategies
+- Issue template formats
+
+**examples.md** - Read when you need:
+
+- Working audit examples
+- Sample issue/PR formats
+- Real-world usage patterns
+- Output format examples
+
+## Configuration
+
+Override defaults via environment or prompt:
+
+- `AUDIT_PARALLEL_LIMIT`: Max concurrent worktrees (default: 8)
+- `AUDIT_SEVERITY_THRESHOLD`: Minimum severity to create issue (default: medium)
+- `AUDIT_MODULE_LOC_LIMIT`: Flag modules exceeding this LOC (default: 300)
