Improve Meilisearch and CrowdSec documentation

incus-meilisearch-manual.md:
- Add production config file settings (config.toml)
- Add Master Key requirements (min 16 bytes, 32 recommended)
- Add API key management section (Master/Admin/Search separation)
- Add snapshot and dump backup/restore procedures
- Add client usage examples (JavaScript, Python)

incus-crowdsec-architecture.md:
- Add Bouncer auto-registration via environment variables
- Add Docker Compose example with BOUNCER_KEY_<name>
- Add Docker Secrets approach for secure key management
- Add acquisition directory structure (/etc/crowdsec/acquis.d/)
- Add service-specific acquisition file examples

+#### CrowdSec Bouncer (수동 등록)
 ```yaml
 API_URL: http://10.90.135.49:8080
 API_KEY: s0ENc/6Tw+6m6tr0Qkjt/WAYU1QlC5/MzH7SQOCJX50

+#### Bouncer 자동 등록 (권장)
+
+> 컨테이너 시작 시 환경변수로 Bouncer 자동 등록. 수동 `cscli bouncers add` 불필요.
+
+**환경변수 방식**:
+```bash
+# CrowdSec 컨테이너 시작 시 Bouncer 자동 등록
+incus launch docker.io/crowdsecurity/crowdsec crowdsec \
+  --config environment.BOUNCER_KEY_openresty=my-secure-bouncer-key-here \
+  --config environment.BOUNCER_KEY_firewall=another-bouncer-key-here
+```
+
+**Docker Compose 예시**:
+```yaml
+services:
+  crowdsec:
+    image: crowdsecurity/crowdsec:latest
+    environment:
+      # Bouncer 자동 등록 (BOUNCER_KEY_<name>=<key>)
+      - BOUNCER_KEY_openresty=${OPENRESTY_BOUNCER_KEY}

+    depends_on:
+      - crowdsec
+```
+
+**Docker Secret 방식 (더 안전)**:
+```yaml
+services:
+  crowdsec:
+    image: crowdsecurity/crowdsec:latest
+    secrets:
+      - bouncer_key_openresty
+      - bouncer_key_firewall
+    # Secret 파일은 /run/secrets/bouncer_key_<name> 으로 마운트됨
+
+secrets:
+  bouncer_key_openresty:
+    file: ./secrets/openresty_bouncer_key
+  bouncer_key_firewall:
+    file: ./secrets/firewall_bouncer_key
+```
+
+```bash
+# Secret 파일 생성
+mkdir -p secrets
+openssl rand -base64 32 > secrets/openresty_bouncer_key
+openssl rand -base64 32 > secrets/firewall_bouncer_key
+chmod 600 secrets/*
+```
+
+> **주의**: 환경변수/Secret 방식은 초기 배포 시에만 동작. 기존 Bouncer 업데이트는 `cscli` 사용.
