Import statements: 277 files, 548 occurrences replaced

Database & Docker:
- PostgreSQL user/db: planarchy → capakraken
- Docker volumes: planarchy_pgdata → capakraken_pgdata
- Connection strings updated in docker-compose, .env, CI

CI/CD:
- GitHub Actions workflow: all filter commands updated
- Test database credentials updated

Infrastructure:
- Redis channel: planarchy:sse → capakraken:sse
- Logger service name: planarchy-api → capakraken-api
- Anonymization seed updated
- Start/stop/restart scripts updated

Test data:
- Seed emails: @planarchy.dev → @capakraken.dev
- E2E test credentials: all 11 spec files updated
- Email defaults: @planarchy.app → @capakraken.app
- localStorage keys: planarchy_* → capakraken_*

Documentation: 30+ .md files updated
