Major improvements: multi-stage Docker, security hardening, host metrics, tests
- Multi-stage Docker build: Dockerfile compiles frontend (Node.js) and
backend (Gradle) inside Docker; no local Java/Node.js required
- Security hardening: replaced full host root mount with specific
directory mounts (/proc, /sys, /etc, /var, /home, /opt, /tmp, /srv, /usr)
- Host metrics consistency: LinuxMemoryService and CpuDetailsService now
read from /host/proc instead of container OSHI
- Concurrency: replaced synchronized with AtomicReference in 3 services
- Global error handling: added @RestControllerAdvice for JSON error responses
- Unit tests: added 32 tests for /proc parsers, CPU usage, process uptime
- Docker security: non-root user, read-only FS, no-new-privileges, healthcheck
- Debug logging: added log.debug() in silent catch blocks
- Documentation: updated README, INSTALLATION, DEVELOPMENT, CONFIGURATION,
ARCHITECTURE, CHANGELOG
