Add /modernize-project command - Multi-agent orchestrator (v2.3.0)

[laird]

Added comprehensive project modernization command that orchestrates a team of 6 specialist agents through a systematic 7-phase upgrade process.

New Command: /modernize-project

Coordinates Migration Coordinator, Security Agent, Architect Agent, Coder Agent, Tester Agent, and Documentation Agent to modernize any software project.

7-Phase Systematic Approach

Phase 0: Discovery & Assessment (1-2 days)

• Project analysis and dependency inventory
• Security baseline scan (BLOCKING)
• Technology assessment
• Test baseline capture

Phase 1: Security Remediation (2-5 days)

• Fix CRITICAL/HIGH CVEs (BLOCKING)
• Update insecure dependencies
• Achieve security score ≥45
• Validate with tests (100% pass rate required)

Phase 2: Architecture & Design (2-3 days)

• Framework upgrade planning
• Dependency strategy
• ADR creation for major decisions
• Risk assessment

Phase 3: Framework & Dependency Modernization (5-10 days)

• Upgrade to latest stable framework
• Update all dependencies
• Fix breaking changes
• Parallel execution by module (if possible)

Phase 4: API Modernization & Code Quality (3-7 days)

• Replace obsolete APIs
• Apply modern language features
• Enhance test coverage (target ≥85%)
• Code quality improvements

Phase 5: Performance Optimization (2-4 days)

• Performance profiling
• Optimize critical paths
• Benchmark validation
• Ensure no regressions (≤10%)

Phase 6: Comprehensive Documentation (2-3 days)

• CHANGELOG creation
• Migration guide (800+ lines)
• Update README and docs
• ADR summaries

Phase 7: Final Validation & Release (1-2 days)

• Complete test suite (100% pass rate MANDATORY)
• Final security scan
• Production readiness GO/NO-GO decision

Key Features

• Quality Gates: Security, testing, build, and documentation gates block progression
• Parallel Execution: Multiple coder agents can work on independent modules
• Fix-and-Retest Cycles: Systematic issue resolution with validation
• Complete Audit Trail: All work logged to HISTORY.md
• Universal: Works with any language/framework (.NET, Node.js, Python, etc.)

Example Usage

User: /modernize-project
User: Upgrade my .NET 6 project to .NET 9, fix all CVEs, and achieve 95%+ test coverage

Estimated Timeline

• Small projects (<10k LOC): 18-22 days
• Medium projects (10k-50k LOC): 25-30 days
• Large projects (>50k LOC): 30-36 days
