Issues found during scenario testing:
1. Version propagation: The hostagent and dockeragent packages were
reporting their own Version (0.1.0-dev) instead of the unified
agent's version. Added AgentVersion config field to pass the
parent's version down.
2. macOS legacy cleanup: The install.sh script was missing cleanup
for pulse-docker-agent on macOS.
3. Windows legacy cleanup: The install.ps1 script was missing cleanup
for legacy PulseHostAgent and PulseDockerAgent services.
These fixes ensure:
- Unified agent reports consistent version across host/docker metrics
- Legacy agents are properly removed on all platforms during upgrade
- Users migrating from legacy agents get a clean transition
Implement self-update capability for the unified pulse-agent binary:
- Add internal/agentupdate package with cross-platform update logic
- Hourly version checks against /api/agent/version endpoint
- SHA256 checksum verification for downloaded binaries
- Atomic binary replacement with backup/rollback on failure
- Support for Linux, macOS, and Windows (10 platform/arch combinations)
Build and release changes:
- Dockerfile builds unified agent for all platforms
- build-release.sh includes unified agent in release artifacts
- validate-release.sh validates unified agent binaries
- Install scripts (install.sh, install.ps1) use correct URL format

Fixes#755. Adds interactive pauses and graphical popups (where available) to installer scripts when critical errors occur, ensuring troubleshooting guides are readable. Also clarifies 'build from source' instructions.
