refactor(topics): 멀티 에이전트용 지식 재편 — _Common(공통 기본기) + Domain_* 구조

에이전트 8종(대화형/프로그래머 C·S/디자이너/설계자/기획자/QA/PD/PM)에게
[공통 기본 능력 + 롤별 Specialty] 2층으로 지식을 주입하기 위한 재분류.
문서 내용·포맷은 무수정, 폴더 이동만 (6,372개 문서 수 보존 확인).

- Topic_Programming → Domain_Programming (내부 구조 보존)
- Topic_Graphic → Domain_Design
- Topic_Business → Domain_Product
- Topic_General → Domain_General
- _Common 신설: Math(구 Topic_Math_Specialty), Reasoning(구 General/From_Thinking & Reasoning),
  Reasoning_Creativity(구 General/From_창의성), Communication(Poetic_Blog_Writing + From_writing)
- 타 도메인의 From_* 폴더는 유지 (출처 표기일 뿐, 이미 도메인에 맞게 분류된 문서)
- 빈 폴더 정리 (memory/procedures)
- 에이전트→폴더 매핑은 workspace의 .astra/agent-knowledge-map.json (9개 에이전트)

# Project Profile (Repo Metadata Document)
## 매 한 줄
> **"매 single-page document that answers: what is this repo, who runs it, how do I run it, where is it deployed"**. 2026 modern engineering — replaces sprawling wiki tribal knowledge with a versioned, reviewable, machine-parseable PROJECT.md / project-profile.md at repo root, consumed by humans 와 LLM coding agents (Claude Code, Copilot Workspace) alike.
## 매 핵심
### 매 mandatory sections
- **Identity**: name, slug, owners (tech + product), Slack channel, on-call rotation.
- **Purpose**: 1-paragraph "why this repo exists" — business problem, not implementation.
- **Stack**: languages, frameworks, runtime versions, key dependencies.
- **Run locally**: prereqs + 3-5 commands max to bootstrap dev env.
- **Deploy**: target environments, deploy mechanism (CI workflow link), rollback procedure.
### 매 secondary sections
- **Architecture diagram**: mermaid / draw.io link.
- **Data flows**: what services this calls, who calls this.
- **SLOs**: latency / availability targets.
- **Runbooks**: links to incident-response docs.
- **ADR index**: link to `doc/adr/README.md`.
### 매 LLM agent consumption
- LLM coding agents (Claude Opus 4.7, GPT-5 Workspace) read PROJECT.md FIRST when entering a repo.
- Frontmatter machine-parseable — agents pull tech_stack, owners, conventions.
- Reduces hallucinated assumptions (wrong test runner, wrong deploy target, etc.).
### 매 응용
1. New-hire onboarding (day-1 read).
2. Incident response (on-call finds owner / runbook fast).
3. LLM agent context-priming (agent reads profile → executes commands correctly).
4. Cross-team integration (team A wants to consume team B's service — reads profile first).
## 💻 패턴
### Minimal profile (markdown)
```markdown
---
name: orders-service
slug: orders
owners:
tech: alice@acme.com
product: bob@acme.com
slack: "#orders-team"
oncall: pagerduty.com/services/orders
stack:
language: go
runtime: 1.23
framework: chi
db: postgres-16
---
# orders-service
## Purpose
Authoritative store for customer orders. Handles checkout, fulfillment events.
## Run locally
```bash
make dev
curl localhost:8080/healthz
```
## Deploy
Auto-deploy on merge to `main` via `.github/workflows/deploy.yml`.
Rollback: `gh workflow run rollback.yml -F sha=<prev>`.
## Architecture
See [docs/architecture.md](docs/architecture.md).
## ADRs
See [doc/adr/](doc/adr/).
```
### Frontmatter spec (YAML, agent-readable)
```yaml
---
name: <kebab-case>
slug: <short>
version: 1
owners:
tech: <email>
product: <email>
security: <email>
slack: "#channel"
oncall: <pagerduty-url>
repo: github.com/acme/orders-service
stack:
language: <go|rust|python|ts>
runtime: <version>
framework: <name>
db: <postgres-16|dynamo|...>
deploy:
prod: <url>
staging: <url>
ci: .github/workflows/deploy.yml
slo:
latency_p99_ms: 250
availability: 99.9
---
```
### CI: profile schema validation
```yaml
# .github/workflows/profile-lint.yml
name: profile-lint
on: [pull_request]
jobs:
lint:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- run: pip install pyyaml jsonschema
- run: python scripts/lint_profile.py PROJECT.md
```
```python
# scripts/lint_profile.py
import sys, yaml, jsonschema
schema = yaml.safe_load(open("schemas/project-profile.schema.yaml"))
text = open(sys.argv[1]).read()
fm = yaml.safe_load(text.split("---")[1])
jsonschema.validate(fm, schema)
print("ok")
```
### Org-wide profile aggregator
```python
# tools/aggregate_profiles.py
import requests, yaml, pathlib
ORG = "acme"
gh = requests.Session()
repos = gh.get(f"https://api.github.com/orgs/{ORG}/repos").json()
out = []
for r in repos:
raw = gh.get(f"https://raw.githubusercontent.com/{ORG}/{r['name']}/main/PROJECT.md")
if raw.status_code == 200 and "---" in raw.text:
out.append(yaml.safe_load(raw.text.split("---")[1]))
pathlib.Path("catalog.yaml").write_text(yaml.dump(out))
```
### Mermaid embed (architecture)
```markdown
## Architecture
```mermaid
flowchart LR
client --> gateway
gateway --> orders[orders-service]
orders --> postgres[(postgres)]
orders --> kafka[(kafka)]
kafka --> fulfillment
```
```
## 매 결정 기준
| 상황 | Approach |
|---|---|
| Solo repo | Skip — README is enough |
| Service in team org | Mandatory PROJECT.md w/ frontmatter |
| Regulated org (SOC2, FDA) | Profile + ADR index + SLO doc |
| Multi-team monorepo | One profile per service dir |
| LLM-agent-heavy workflow | Frontmatter strict-schema validated in CI |
**기본값**: PROJECT.md at repo root, YAML frontmatter, CI lint, kept under 200 lines.

## 🤖 LLM 활용
**언제**: Repo has > 1 contributor, repo is consumed by LLM coding agents, repo deploys to production.
**언제 X**: Throwaway scratch repo, single-script gist, ephemeral demo.
## ❌ 안티패턴
- **Stale profile**: Owner left 6 months ago, still listed — periodic CODEOWNERS sync needed.
- **Profile-as-novel**: 800-line PROJECT.md — split into ARCHITECTURE.md / RUNBOOK.md.
- **No frontmatter**: Free-form prose only — LLM agents can't reliably extract.
- **Docs-only, no CI lint**: Schema drift goes undetected for months.
## 🧪 검증 / 중복
- Verified (Backstage Software Catalog spec; GitHub `.github/PROJECT.md` convention; Spotify Tech Radar; Anthropic Claude Code agent repo onboarding behavior 2026).
- 신뢰도 A.
