IPv4 connections are retried forever in heartbeat_sender if open() fails,
so a temporary network outage does not terminate the sender.
IPv6 connections that have never opened successfully are dropped after
IPV6_EARLY_FAIL_LIMIT (3) consecutive failures so that a network without
IPv6 support does not keep a dead sender running.
At startup all resolved connections are added to the list regardless of
whether the initial open() succeeds; the heartbeat_sender loop handles
the first real connection attempt.

- watch: true (default) per host; watch: false suppresses all notifications
for that host in udp.py and threshold.py
- Live Dashboard and Host Overview now show only hosts where the logged-in
user is owner or manager (admins see all); WebSocket broadcasts filtered
per-connection by the same rule
- Add hbd/client/plugins/zfs_monitor.py: collects per-pool health, capacity,
fragmentation, dedup ratio, and cumulative I/O ops/bandwidth via zpool(8)

Sets dorestart and triggers a clean shutdown; os.execv re-execs
the process with the original arguments after cleanup.

- scripts/hbc_mini.py: self-contained hbc with no external deps; uses
/proc for CPU/memory/network on Linux, df for disk, JSON config
- hbc + hbc_mini: mark connection _dead and stop sending on protocol error
- README: document hbc_mini usage, config, and plugin availability
- pyproject.toml: include hbc_mini.py in script-files

Server now sends a bare UPD command; client runs hb_install.sh to
reinstall from the package registry, then restarts. hb_install.sh
also copies itself alongside hbc on client installs.

After daemonize() redirects stderr to /dev/null, the existing StreamHandler
writes to /dev/null. logging.basicConfig() is a no-op when handlers are
already configured, so log messages are silently lost.
Replace the daemon block to:
1. Call daemonize() first
2. Explicitly remove existing handlers (pointing to /dev/null)
3. Add SysLogHandler pointing to /dev/log with fallback to UDP localhost:514
4. Log startup message to the new syslog handler
Removes redundant syslog.openlog() call which is no longer needed.

When NagiosRunnerPlugin has no commands configured, set skip_reason before
returning False from initialize(). This allows PluginLoader to log INFO
(not WARNING) when the plugin is skipped.

CLIENT_DEFAULTS seeds "plugins": {} so raw_config.get("plugins", raw_config)
always returned the empty subdict instead of falling back to the full config.
Plugins configured at top-level (e.g. nagios_runner: ...) were therefore
never found, resulting in "No Nagios commands configured".
Now checks the plugins subdict first, then top-level keys, so both
config layouts work correctly.

- Restructuring of the project directory into client and server components
- Renaming of modules and classes to better reflect their purpose and functionality
- Moving common utilities and configurations to a shared location
- Updating import statements to reflect the new structure
- Adding new documentation files for better clarity on various aspects of the project
- Removing deprecated or unused code to streamline the codebase
- Ensuring that all existing functionality is preserved and that the codebase remains functional after the refactoring.
