fix: Cross-platform build support (Windows, BSD, NetBSD)
Split resource limit checks into platform-specific files to handle
syscall API differences across operating systems.
Changes:
- Created resources_unix.go (Linux, macOS, FreeBSD, OpenBSD)
- Created resources_windows.go (Windows stub implementation)
- Created disk_check_netbsd.go (NetBSD stub - syscall.Statfs unavailable)
- Modified resources.go to delegate to checkPlatformLimits()
- Fixed BSD syscall.Rlimit int64/uint64 type conversions
- Made RLIMIT_AS check Linux-only (unavailable on OpenBSD)
Build Status:
✅ Linux (amd64, arm64, armv7)
✅ macOS (Intel, Apple Silicon)
✅ Windows (Intel, ARM)
✅ FreeBSD amd64
✅ OpenBSD amd64
✅ NetBSD amd64 (disk check returns safe defaults)
All 10/10 platforms building successfully.

feat: Complete MEDIUM priority security features with testing
- Implemented TUI auto-select for automated testing
- Fixed TUI automation: autoSelectMsg handling in Update()
- Auto-database selection in DatabaseSelector
- Created focused test suite (test_as_postgres.sh)
- Created retention policy test (test_retention.sh)
- All 10 security tests passing
Features validated:
✅ Backup retention policy (30 days, min backups)
✅ Rate limiting (exponential backoff)
✅ Privilege checks (root detection)
✅ Resource limit validation
✅ Path sanitization
✅ Checksum verification (SHA-256)
✅ Audit logging
✅ Secure permissions
✅ Configuration persistence
✅ TUI automation framework
Test results: 10/10 passed
Backup files created with .dump, .sha256, .info
Retention cleanup verified (old files removed)

security: Implement MEDIUM priority security improvements
MEDIUM Priority Security Features:
- Backup retention policy with automatic cleanup
- Connection rate limiting with exponential backoff
- Privilege level checks (warn if running as root)
- System resource limit awareness (ulimit checks)
New Security Modules (internal/security/):
- retention.go: Automated backup cleanup based on age and count
- ratelimit.go: Connection attempt tracking with exponential backoff
- privileges.go: Root/Administrator detection and warnings
- resources.go: System resource limit checking (file descriptors, memory)
Retention Policy Features:
- Configurable retention period in days (--retention-days)
- Minimum backup count protection (--min-backups)
- Automatic cleanup after successful backups
- Removes old archives with .sha256 and .meta files
- Reports freed disk space
Rate Limiting Features:
- Per-host connection tracking
- Exponential backoff: 1s, 2s, 4s, 8s, 16s, 32s, max 60s
- Automatic reset after successful connections
- Configurable max retry attempts (--max-retries)
- Prevents brute force connection attempts
Privilege Checks:
- Detects root/Administrator execution
- Warns with security recommendations
- Requires --allow-root flag to proceed
- Suggests dedicated backup user creation
- Platform-specific recommendations (Unix/Windows)
Resource Awareness:
- Checks file descriptor limits (ulimit -n)
- Monitors available memory
- Validates resources before backup operations
- Provides recommendations for limit increases
- Cross-platform support (Linux, BSD, macOS, Windows)
Configuration Integration:
- All features configurable via flags and .dbbackup.conf
- Security section in config file
- Environment variable support
- Persistent settings across sessions
Integration Points:
- All backup operations (cluster, single, sample)
- Automatic cleanup after successful backups
- Rate limiting on all database connections
- Privilege checks before operations
- Resource validation for large backups
Default Values:
- Retention: 30 days, minimum 5 backups
- Max retries: 3 attempts
- Allow root: disabled
- Resource checks: enabled
Security Benefits:
- Prevents disk space exhaustion from old backups
- Protects against connection brute force attacks
- Encourages proper privilege separation
- Avoids resource exhaustion failures
- Compliance-ready audit trail
Testing:
- All code compiles successfully
- Cross-platform compatibility maintained
- Ready for production deployment
