docs: add native Japanese translation of ECC documentation (ja-JP)

Translate everything-claude-code repository to Japanese including:
- 17 root documentation files
- 60 agent documentation files
- 80 command documentation files
- 99 rule files across 18 language directories (common, angular, arkts, cpp, csharp, dart, fsharp, golang, java, kotlin, perl, php, python, ruby, rust, swift, typescript, web)
- 199 skill documentation files

Total: 455 files translated to Japanese with:
- Consistent terminology glossary applied throughout
- YAML field names preserved in English (name, description, etc.)
- Code blocks and examples untouched (comments translated)
- Markdown structure and relative links preserved
- Professional translation maintaining technical accuracy

This translation expands ECC accessibility to Japanese-speaking developers and teams.

+# Enterprise Agent Ops
+
+Use this skill for cloud-hosted or continuously running agent systems that need operational controls beyond single CLI sessions.
+
+## Operational Domains
+
+1. runtime lifecycle (start, pause, stop, restart)
+2. observability (logs, metrics, traces)
+3. safety controls (scopes, permissions, kill switches)
+4. change management (rollout, rollback, audit)
+
+## Baseline Controls
+
+- immutable deployment artifacts
+- least-privilege credentials
+- environment-level secret injection
+- hard timeout and retry budgets
+- audit log for high-risk actions
+
+## Metrics to Track
+
+- success rate
+- mean retries per task
+- time to recovery
+- cost per successful task
+- failure class distribution
+
+## Incident Pattern
+
+When failure spikes:
+1. freeze new rollout
+2. capture representative traces
+3. isolate failing route
+4. patch with smallest safe change
+5. run regression + security checks
+6. resume gradually
+
+## Deployment Integrations
+
+This skill pairs with:
+- PM2 workflows
+- systemd services
+- container orchestrators
+- CI/CD gates
