chore(rebar): Pier_T_rebar 작업 폴더 초기 구성 및 외부 의존 파일 통합

- Code\rebar_pipeline, review_pipeline, pier-program을 정션에서 실제 폴더로 전환
- Code\rhino_mcp 및 CLAUDE_rhino배경.md 추가, .mcp.json은 PYTHONPATH로 새 위치 사용
- pier-program 내부 .git 제거(이력은 backup\pier-program_20261028.bundle에 보관)
- worktree 가이드 반영(CLAUDE.local.md, HANDOFF.md)
- D:\Rhino-MCP 경로 참조를 새 위치로 치환

+# PM Agent Team - Product Discovery & Strategy
+
+> Automated PM analysis pipeline: Discovery + Strategy + Research -> PRD
+> Based on [pm-skills](https://github.com/phuryn/pm-skills) by Pawel Huryn (MIT License)
+
+## Overview
+
+PM Agent Team provides AI-powered product management analysis for solo developers
+and small teams without a dedicated PM. It runs before the PDCA Plan phase to ensure
+you're building the right thing.
+
+## How It Works
+
+```
+/pdca pm {feature}
+     |
+     v
+PM Lead (leader-agent) - orchestrates
+     |
+     +-- pm-discovery  --> Opportunity Solution Tree
+     +-- pm-strategy   --> Value Proposition + Lean Canvas     [parallel]
+     +-- pm-research   --> Personas + Competitors + Market
+     |
+     v
+pm-prd --> Beachhead + GTM + PRD (8-section)
+     |
+     v
+docs/00-pm/{feature}.prd.md
+     |
+     v
+Next: /pdca plan {feature} (PRD auto-referenced)
+```
+
+## Included PM Frameworks (8)
+
+| Framework | Agent | Origin |
+|-----------|-------|--------|
+| Opportunity Solution Tree | pm-discovery | Teresa Torres |
+| Value Proposition (JTBD 6-Part) | pm-strategy | Huryn & Abdul Rauf |
+| Lean Canvas | pm-strategy | Ash Maurya |
+| User Personas (JTBD) | pm-research | JTBD-based |
+| Competitor Analysis | pm-research | Strategic positioning |
+| Market Sizing (TAM/SAM/SOM) | pm-research | Dual-method |
+| Beachhead Segment | pm-prd | Geoffrey Moore |
+| GTM Strategy | pm-prd | Product Compass |
+
+## Usage
+
+```bash
+# Run PM analysis
+/pdca pm my-saas-app
+
+# After PM analysis, continue with PDCA
+/pdca plan my-saas-app    # PRD auto-referenced
+/pdca design my-saas-app
+/pdca do my-saas-app
+```
+
+## Requirements
+
+- Agent Teams enabled: `HMCMKIT_EXPERIMENTAL_AGENT_TEAMS=1`
+- Project level: Dynamic or Enterprise (Starter not supported)
+
+## PDCA Integration
+
+```
+[PM] --> [Plan] --> [Design] --> [Do] --> [Check] --> [Act] --> [Report]
+ ^        ^
+ new      PRD auto-referenced in Plan
+```
+
+When `/pdca plan {feature}` runs after PM analysis:
+1. Checks for `docs/00-pm/{feature}.prd.md`
+2. If found, reads PRD and uses as context for Plan document
+3. Plan document quality is significantly improved with PM-backed data
+
+## Output
+
+PRD document saved to `docs/00-pm/{feature}.prd.md` containing:
+- Executive Summary (4-perspective)
+- Opportunity Solution Tree
+- Value Proposition + Lean Canvas
+- User Personas (3) + Competitor Analysis (5) + Market Sizing
+- Beachhead Segment + GTM Strategy
+- Product Requirements (8-section PRD)
